XF 1.2 What could cause an internal server errror (500) on a thread and how to resolve it?

If it is just that thread then it could be something to do with mod security.

Try disabling that and checking to see if it still happens.
If not, then something in the thread or title is triggering it.

The BBCode Manager Extion was the problem, I removed it, because I never realy used it.

But it is weird that it only affected this one thread.

That's odd, but I can't see the thread to determine it. I've seen and debugged a site receiving a 500 error caused by BB Code parsing, not sure what it is that actually causes it tho.
