I used PHP’s flock(), or file locking, method to fix the problem. It’s a few milliseconds slower, but it’s worth not losing all your comments! If you don’t plan on extending the Comments class at all, it can be optimized to read quicker by saving the results in the constructor function.

As this has nothing to do with JibberBook’s core, its version number will remain at 2.0.

It’s frustrating not knowing what’s causing a problem, and for a while, I just ignored it. But then it popped up again in another site! This time it only happened to one page. That should narrow it down, I thought. I’ll just compare this page with one that works and isolate the problem. That didn’t quite work out because I focused on the wrong area. I thought the problem all along was using some simplexml functions in php, and when I found a difference in the way I looped through some data, I thought that was it. It wasn’t. Then I started getting mad and taking out random things. Suddenly, when I commented out an include that checks the session to see whether someone is logged in or not, it worked! But I kind of needed that bit. So I started taking out other stuff, this time in the html.

And then I found it. The evil little monster, the source of my nightmares, the thorn in my side! Gaze upon it if you can muster the courage!

This line of code was generated from the template file I used in PSPad. I don’t have much knowledge of meta tags or why it would break only IE. Maybe it has something to do with caching, I don’t know. All I know is that my pages work now. If any of you know, please leave a comment.
