Possible Causes and Fixes for the "HTTP Error" When Uploading Files in WordPress

Mon, 30 Jan 2017 01:37:25 +0000

If you use WordPress, you may occasionally run into the “HTTP error” problem when uploading images. Search online and you’ll find all sorts of explanations — some say it’s a file permission issue, others say you need to add a snippet of code to your theme. In fact, all of these are “possible” causes. The most correct approach is to check the server’s error log to determine what the actual cause is. I happened to run into this problem today, so let me put together my solution along with other possible causes!

[CMS] Why Do Plugins Slow Down Page Loads and Hurt Server Performance?

Sun, 17 Apr 2011 09:00:37 +0000

Anyone who builds a site with a CMS (such as WordPress, Drupal, or Joomla) has probably heard the saying: use fewer plugins and your site will load much faster. For example, if I want a Lightbox effect on my site, I can manually add the jQuery code, or I can just install a plugin. Both methods achieve the same result, but they can make a noticeable difference in how fast the site loads.

How Do I Manually Enable and Disable WordPress Maintenance Mode?

Mon, 14 Feb 2011 09:00:32 +0000

Maintenance mode seems to have been introduced around WordPress 3.0. When your WordPress is being updated, it automatically enters maintenance mode to keep visitors from seeing error messages. I had actually been looking forward to this feature for a long time, because almost every other mature CMS has it — Xoops, for example, lets you temporarily shut down your site, and the well-known forum software Discuz! can also temporarily close a forum and restrict access to specific users. WordPress's maintenance mode, though, isn't very good yet: you can't enable it manually. It only turns on automatically while files are being updated. This article will show you how to enable maintenance mode by hand.

WordPress Plugin & Theme Installation Tutorial (For WP 2.9 and Below)

Tue, 01 Jun 2010 13:36:01 +0000

Someone asked me the other day what WordPress can do. That's actually a hard question to answer, because WordPress is extremely extensible — you can use plugins to add all sorts of features to your blog, and you can even make your blog not look like a blog at all ^^ WordPress also lets users install themes to dress up their blog nicely. If your skills are good enough, you can design your own theme too, but that's not what this article covers. This article is mainly about how to install plugins and themes.

WordPress Installation Tutorial — The World's Most Popular Blogging (Blog) Site-Building Software (This tutorial applies to WP 2.9 and earlier)

Mon, 31 May 2010 11:02:53 +0000

~~You ask me how deep my love is, how much I love you?~~ (just kidding~) You ask me what I think is the best blogging software in the world for building a site? I’ll definitely tell you it’s WordPress. It’s not just because my own blog is built with WordPress that I say this. Back when I was choosing what software to use to build Wind Chaser, I considered using something like Xoops paired with plugins to construct a blog, and I also tried LifeType, the blogging software the school uses, but neither was very good. LifeType’s interface in particular was really unbearable, extremely unfriendly, and it had our English teacher dropping by every so often to ask me how to read replies, how to publish a post… On top of that, LifeType’s extensibility isn’t as good as WordPress’s. Anyway, WordPress is just the best ^^ If you don’t believe me, try installing it yourself~~

Broken Link Checker - Automatically Find Dead Links and Broken Images in WordPress

Fri, 28 May 2010 00:05:48 +0000

When you look for files online, you often run into an annoying situation: you finally find the file you want, click the link, and get… “This page has been removed. Please contact the site administrator.” It’s really frustrating. But it’s not entirely the webmaster’s fault. Once a website grows, it has a lot of outgoing links, and the webmaster can’t check every one of them by hand. Some webmasters ask users to report broken links, but I don’t think that works well. Someone who has already hit a dead link is annoyed enough. Why would they bother reporting it? Here I want to introduce Broken Link Checker, a plugin made specifically for WordPress. It automatically checks your WordPress blog for broken links and broken images (the broken-image icons that Chinese speakers jokingly call “steamed buns”). Broken Link Checker can also email you when a broken link appears on your blog. It’s very convenient, but I’d recommend that first-time installers don’t turn that feature on right away. Many people find over a thousand broken links or images the first time they run it, and their inbox gets flooded XD

WordPress 2.9 - Quite a Few New Features Added, No Major Issues in My Own Testing

Sat, 19 Dec 2009 16:11:03 +0000

After I got up today and logged into 逐風者, I saw a very important message on the login screen - WordPress 2.9 has been released. And this time it isn’t just a bunch of bug fixes; quite a few features have been added too. Based on my own testing, WordPress 2.9 doesn’t have any major problems, so everyone can go ahead and update right away!!

Top 10 WordPress Security Tips

Sat, 14 Nov 2009 22:51:54 +0000

As the saying goes, the tall tree catches the wind. WordPress is the most widely used blogging platform in the world, so it's also a prime target for hackers everywhere. Strengthening your WordPress security is something every blogger has to do. WordPress releases security updates every so often, but keeping your site safe also depends on you. A Japanese organization once studied computer incidents (computers being attacked) and found that a large share of them came from user mistakes rather than from problems with the system itself. So in this post, I'll borrow an article from the Chinese blog Moonlight Blog to show you how to check whether your WordPress installation is secure enough.

WP Security Scan - Scan Your WordPress for Vulnerabilities

Sat, 14 Nov 2009 16:39:56 +0000

WP Security Scan is a WordPress plugin that scans your site and reports WordPress vulnerabilities. If you host your own site, you probably already know that before setting things up you need to configure file permissions — things like 777 and 655. What WP Security Scan actually does is check whether your file permissions are set correctly, and it can also check and change your database prefix. It's a great fit for beginners.

Gzippy - Enabling Gzip (Web Page Compression) in WordPress

Sun, 18 Oct 2009 11:14:26 +0000

In this post I’ll show you how to enable WordPress’s Gzip feature with the Gzippy plugin. First, a heads-up: not every hosting account supports Gzip. If your host doesn’t support it and you install Gzippy anyway, your site may break. If that happens, just remove Gzippy via FTP! So what’s the benefit of installing Gzippy? Of course there is, otherwise why would I bother XD. Gzip is simply web page compression. It can make your web pages smaller. A page that’s 100K might shrink to about 30K after Gzip compression, which makes pages load a lot faster.

Plugin name: Gzippy

Official website: http://wordpress.org/extend/plugins/gzippy/

Download link: http://downloads.wordpress.org/plugin/gzippy.1.0.2.1.zip

WP-Polls: A Poll Plugin Made for WordPress

Sun, 18 Oct 2009 10:18:00 +0000

Today, the site admin Tingfeng is going to introduce a plugin called WP-Polls. WP-Polls gives your blog Ajax-based polling, and it is completely free, has no restrictions, and won't slow your site down. You might worry that WP-Polls's theme isn't pretty enough, but that's not a problem either, because you can set WP-Polls's own theme and color scheme.

WordPress 2.8.1 RC

Wed, 08 Jul 2009 11:14:51 +0000

Yesterday when I logged into 逐風者, I was surprised to find that WordPress 2.8.1 RC was already out. It’s only an RC release, but at least it’s better than a beta. This time it doesn’t add many features — it just brings the visual editor back from the dead (in 2.8 the visual editor would disappear). Other than that, I didn’t notice any particularly special updates. If you want to try it out, go download it now.

Inserting a "Continue Reading" Tag in WordPress Posts

Tue, 07 Jul 2009 13:54:44 +0000

Today I’m going to teach you a handy little trick: the more tag. Anyone who has just set up WordPress has probably noticed that WordPress doesn’t have a built-in feature to display only a few lines of a post, so every post shows up in full on the homepage, which makes the homepage look pretty ugly. In fact, there is a way to insert a continue reading tag, and it’s built into WordPress. I have to admit, when I first started I used it as an <hr> tag XD

Let’s take a look at what it does first!

WordPress 2.8.1 Beta

Sun, 21 Jun 2009 14:12:27 +0000

WordPress 2.8.1 Beta is out!

But personally I don’t quite dare to try it yet, because after I installed 2.8 last time the visual editor disappeared

and a whole bunch of other problems………….?

Even though 2.8.1 is out this time, it’s only a beta, so it’s hard to say how stable it is

I don’t want to waste time downgrading XD

If you want to use it, go ahead and grab it!

Subscribe To Comments - Automatically Notify Commenters That Their Comment Got a Reply

Sun, 21 Jun 2009 09:13:26 +0000

Today I want to introduce a plugin called Subscribe To Comments. It can automatically tell commenters that their comment has been replied to, so they don’t have to come back and check for themselves. Subscribe To Comments was recommended to me by Brother Sausage, and since I think it’s pretty useful, I’m sharing it with everyone.

WordPress 2.8 Introduction

Sat, 13 Jun 2009 17:16:13 +0000

Today I finally updated WordPress from 2.7 to 2.8! WordPress 2.8 is said to focus on performance this time, and it doesn’t really add many features, but it does fix a lot of bugs from older versions (more than 700 of them — scary, right?). That said, WordPress 2.8 does still come with some new features (though, as I mentioned above, not many). As for the interface, it might give you the illusion that… the update was just a version number change = =, because this update keeps the same 2.7 admin interface with no obvious changes. That’s roughly all I have to say. Next, let me walk you through a few of the main new features in WordPress 2.8.

Scheduled Posting in WordPress Without Any Plugin

Sun, 31 May 2009 10:55:32 +0000

How do you schedule a post in WordPress? Do you need a plugin? Actually, no — WordPress has a built-in scheduled posting feature, but it is hidden so cleverly that very few people ever find it. I only learned about it after seeing it on someone else’s blog.

So how do you use scheduled posting? Follow the tutorial below and you are guaranteed to get it. If anything is unclear, feel free to ask me in the comments.

WordPress Account & Password Change Tutorial

Sun, 17 May 2009 12:40:18 +0000

Last time we finished setting up WP, and the system gave you a set of account credentials. The only problem is that the password is really hard to remember, and the username is adm, which is easy to guess — that’s a real security risk for your blog. So now let’s show you how to change your username & password.

Changing the username
Log in to your web host’s control panel and click phpMyAdmin.

Introducing WordPress 2.7.1 & Download

Wed, 13 May 2009 18:37:53 +0000

Today I’d like to introduce a package for building blogs — WordPress.

It’s a program that lets you set up a blog very easily.

It’s written in PHP.

In the future, this site will publish more related tutorials.

Its latest version right now is 2.7.1.

One of my favorite features is its heavy use of Ajax.

You don’t have to reload the page every time you organize it.

It also supports a lot of plugins and themes.

So you don’t have to figure out how to lay out your interface yourself.

For people who don’t know CSS, this is a real blessing.

Also, it’s an open-source package.

That means if there’s anything inside it you’re not happy with, you can modify it yourself.

In effect, it gives me a great place to practice web programming.

Here are some things to note when setting up WP.

If you want to set it up on your own host, you just need to install AppServ.

But if you want to put it on a web hosting space,

you first have to make sure the provider offering the space provides PHP and MySQL services.

Without these services, you can’t set it up at all.
