Important Forum borken, possible database access issue?

Kunena version 1.5.11
Joomla version 1.5.8
PHP version 5.2.9
MySql version 5.0.32-Debian_7etch6

The forum has been up and running since installation until mid last week. Since then, users can log into the forum, but once they attempt to view messages, they see a window like the image attached. I'm trying to figure out just where to start looking, if it's a communication issue with the DB, or if something inside the DB became hosed with the messages. Being an older version finding information has been a bit more difficult, and my searches thus far have not been successful.

A 'power admin' I am not, I had done a lot of reading and research putting the site together several years ago which has functioned perfectly until now... and am once again rather 'rusty' so feel free to talk to me like a slow third grader.

Any ideas/suggestions will be much appreciated

G'day, eyeteeth, and welcome to Kunena.

J! 1.5.8 is not supported.

K 1.5.11 is not supported.

It is recommended that you consider upgrading to J! 1.5.23 and K 1.6.4 (see K 1.6 Upgrade Guide )

'borken' nice spelling sheesh... lol

"J! 1.5.8 is not supported.

K 1.5.11 is not supported."

Yea, I realize that, but I'm also hoping someone has seen the problem and it's a quicker fix. The more I think about it, the more I fear it is a database issue and not a Kunena or Joomla problem.

Kunena 1.5.x doesn't show exactly the error, can-you enable debug in Joomla! configuration panel to see what's happen ?

Are-you using default kunena template ? Can-you start by upgrading Joomla! to 1.5.23 ?

My apologies for the delay in response. I thought I had debug enabled, but your post made me double check.

Once debug was on, I was able to track down a solution, and as I figured, it was a simple quick fix. A corrupted table that was able to be repaired.

With that said, I've looked into updating the site to newer releases, but I am at the web hosts mercy as the version of MySQL they have installed is old enough I cannot update Joomla yet.

The site is 'seasonal', so hopefully once winter hits and the traffic dies down, They will have updated the backend, and I can get to work updating Joomla and Kunena.

Thanks for your help.

(BTW... how do you 'bork' a forum anyway?)
