Hi! I am facing problem with my posts in category not showing up. It shows http 500 error. So i cannot read any posts. I do not what is the best approach to find the problem. I check the url. I am not using sef components. The url seems fine and pointing to right place.
Category url
index.php?option=com_fireboard&Itemid=155&func=showcat&catid=2
Here is post url
index.php?option=com_fireboard&Itemid=155&func=view&id=3&catid=2
By the way the setting of the topic is not private nor moderated, just a regular public post category.
Getting to category and topics work fine. But as soon as I choose thread or post it shows error page. I googled around a quite a bit and cannot find anyone having this problem.
Any idea how to solve this.

Does it happen to every post? Do you have access to the server logs? There should be a more descriptive error in the apache error log.

Thank you for the fast reply, Yeah it happens to all posts in all categories. Thanks a lot I fixed it. I looked at my apache error log and

Then I knew someone on my site must have changed that bad word filtering to yes when there was no PHP library installed for that. So I set that back to no and it works perfect. It was funny how i got http 500 error, but no specific php error saying so and so file does not exist.
Great I am pretty sure someone encountered this error before.
