It can be quite hard to track those errors down.

Sometimes there's a useful message in the apache log to tell you what went wrong.  If you have something in there, please post it up here and maybe someone can help.

If there's nothing in the apache log to go on, then I tend to go through a process of editing the script to add some logging and then reloading the page while watching the apache log.  If you do this repeatedly you can eventually find out the file and line number where the error is thrown.

By the way, I've found the most common cause of this error for me is using old code with a database that's already been upgraded.

Good luck!
