Internal Server Errors And Plugins

I’ve been having all sorts of issues with my dashboards ever since WordPress 2.8 came about. I also kept having Internal Server Error 500 pop up from time to time. With 2.8, I actually found a fix for it, and that should have been that.

But with each update, that fix wasn’t working so much. None of my blogs worked well after 2.8 anyway, and we had to keep updating. And the WordPress people kept updating every two weeks, and that was irritating because automatic upgrade wouldn’t work for me. When WordPress 2.8.4 came out, I decided I wasn’t upgrading at all; nope, just wasn’t doing it.

That is, until I started reading all the news about blogs that hadn’t updated being hacked into and basically having all content destroyed. Man, nothing will get you moving faster than scary news like that. So, I finally updated all my blogs; one had already been updated when I was hoping to fix something else, but it hadn’t fixed my issue.

Over the last couple of days I’ve been getting that Internal Server Error thing over and over, and never when doing the same thing. I was going nuts, and I was trying to check plugins and even thought about reloading my software. And I was right on the verge of doing that when I decided, based on research, that it had to be the plugins, or at least some of them.

I started with my business blog, which was having the most issues. I turned off all plugins except Akismet. Then I went to the dashboard; it was working perfectly. Slowly and surely, I added one plugin at a time, to see which one would make the dashboard stop working. I was hoping it was only one, and I was hoping it would be WP Super Cache, which I’d just loaded.

Turns out it was WP Super Cache; but it wasn’t alone.I had to kill four other plugins as well. Those were Broken Link Checker, Gravatar, Why Do Work Adsense, and WP Ajax Edit Comments. I couldn’t believe it was all of them, but there it was. The only one that’s really bothering me a lot is Broker Link Checker, because it works great. The others,… well, I’d like to have them, but I really don’t need them.

I turned on WP Super Cache because my blog had been running a little sluggish, and I thought that would take care of it. Turns out it didn’t do anything, as there was another plugin that was recommended to use with it, but it wouldn’t work on my blogs because, supposedly, my host is running PHP version 4 instead of version 5. I might not have the terminology fully correct, but I have the essence and the numbers correct. Anyway, it didn’t work on this blog, so it doesn’t really matter that I’m removing it, for the second time.

I then went to my finance blog and deactivated the same plugins, if I had them there, and went to the dashboard. There was still a problem. I had a feeling I knew what the problem was, and I was correct; my plugin called Backup WP was the problem. It’s the only blog I had it on, as I use WordPress Database Backup on the other blogs, so I’ll just switch to that and things will be just fine.

Then I came to this blog and did the same thing, and there you are; all is right with the world once more. Now, what I want to make sure I say is that I don’t know that one of these plugins may work well on its own, but doesn’t play well with another plugin that I loaded first. However, I loaded the plugins I really felt I needed first, and if they worked, then I moved on to the next one.

Anyway, now I’ll monitor things over the next few days to see if I get that error again. I hope not; this can be quite tiring. Check out your plugins if you have any problems. Deactivate them all first if you need to, like I did the first time around, and if you have no problems after that, you definitely know it’s a plugin issue. Good luck,

WP Super Cache

There’s a plugin for WordPress called WP Super Cache that I’ve been experimenting with lately. The main purpose of it is to helps speed your WordPress blog up by creating a series of HTML files out of your PHP files, and thus it speeds up your site because PHP can be a heavy load. I’m not going to get into all of the science of it, because frankly I don’t quite get how it works, so instead I’m going to talk about what I’ve seen thus far.

First off, you have to remember to do a little bit of configuring before the plugin works. I’ve noticed that the first time I ran the program, then the second time I’ve decided to run the program (I inactivated it once; I’ll come back to that), I forgot to enable the cache, which it mentions on the plugins page. If you forget to do that, your blog will hang, and it’ll take you forever to get back into it; anyone else, for that matter. Also, there are other choices and recommendations for things to do after you’ve enabled the cache; some I’ve activated, some I haven’t. For instance, you can enable the compression of files, which helps things move faster, and I’ve done that, although it does warn that some ISPs might not work well if you do that; so far, so good. At the same time, I didn’t enable something called Lockdown, which is supposed to protect you against a spike in comments. Trust me, I’ll feel elated with a spike in comments, at least the first time around.

The first time I inactivated the program because my blog started running really slow, and it was the last thing I’d remembered adding at the time. Later on, I thought about the javascript, which I wrote about here, and of course it did turn out to be the javascript issue all along. So, I brought the program back, and things have gone along pretty well.

I did have one more issue, though, which led to my forgetting to enable the cache again. This morning I tried to update my blog to 2.6.5 because of more security flaws, and this blog just wouldn’t load using the WP Automatic Update program. I wondered what was wrong, so I went and updated my other blog, which is also WP, and it worked just fine. I then figured it had to be this plugin, so I inactivated it, and voila. I then reactivated it after the update, and, of course, just now went through that problem of not being able to get to the blog until I enabled the cache; ugh. I wonder how many people tried to come to the blog and couldn’t because of that idiotic mistake. Oh well,…

Right now, the jury is still out on this plugin, but the blog does seem to be moving pretty fast right now. Unfortunately, using this plugin didn’t affect the bad performance of the javascript in any fashion, which was disappointing. However, I’m doing some research on that issue, and if it works out I’ll write about it here, so stay tuned.
