Solved Creating Forum category reveals http 500 internal server error

Hello people

I just came across an issue I can't seem to fix by myself, or find any other thread related to it.

I have setup my joomla installation ( latest 2.5 ) with kunena ( latest 2.0.2 ) and I have configured all my categories and subcategories with no problems whatsoever. I made test posts and threads with no problems.

The modules were working perfectly on the front page displaying latest posts and threads, along with other Joomla modules ( very few as I intend to have it as lightweight as possible ).

But when I needed to create a new directory, the joomla administration took forever to load, resulting in a 500 error. At first it showed that the helper.php on line 522 had a problem ( inside administrator/components/com_kunena/libraries/forum/category/ directory.

After enabling the system debug mode to maximum mode I have this message on my browser :

Fatal error: Access to undeclared static property: JLoader::$classes in /home/DOMAIN/public_html/libraries/loader.php on line 195

( i have removed the domain because the site is still under development and I can't give it to the public because of no consent from my client )

The website functions properly on any link/menu that doesn't have the Kunena component.

In the administration area, the forum categories link provide the same error, but other sections of the kunena admin work.

I have also installed Jomsocial in order to provide me with personal messages, anything else was/is disabled, no profile integrations or anything else.

I am running on nginx 1.2.5 and php 5.3.18

I must state that the forum configuration and categories and the such were replaced into the new installation with those of the previous installation ( an empty one which was for testing purposes ) by replacing the old database prefix with the new one and up until now it had no problems at all. I suspect this could be a cause but I'm not so sure because up until now ( 1-2 months of development and testing on the website ) I have used the new installation with no problems and I can't relate this problem to this cause, except if there's something I forgot to transfer which I highly doubt.

Any help would be greatly appreciated as I'm trying to make this work to no avail and I have a deadline this week and I'm at a loss.

Thank you very much for your time, I'll be available to post any information on the installation etc.

I don't know what is exactly problem, but i try to guessing your problem is not about kunena, it's your server.

BUT sometime to solve that problem, Try open your .htaccess file and find :
# RewriteBase /

uncomment that line and should look like this :
RewriteBase /

Let's me know if that will help you.
If doesn't post your kunena configuration here and wait some advance member help more detail.

Hello and thanks for the reply. I finally did a reinstall after backing up the categories and the problem vanished.

I hope it doesn't happen again though, it's a very big discomfort for such problems to occur, especially when a website goes online.

But I will stick to Kunena because even though it may not be the best forum platform available, I believe the guys working on it are serious on their work and it's a good project to support.
