Unable to revert to old version nor to upgrade to new version.

Thanks in advance.

I do not know the specific cause of whatever is preventing you reverting to the older version of Kunena that you have before all these problems started. My guess is that the Joomla database is corrupted in some way and my suspicion is that the Joomla _assets table is in a state of disrepair.

I asked you before if you had a backup of your website before you attempted to upgrade from you old forum (on J! 2.5.9) to K 3.0.4 and you did not answer my question; rich suggested that you enable Joomla debug mode to see if the upgrade process displayed any messages - debug messages appear at the bottom of the page - and you did not say if there were any messages or not.

It is difficult to determine if a process is actually running or whether there's just the same message displayed. The surest way to end a process is to reboot the webserver.

Can you please answer my earlier question about whether you have a backup of your website (when you were using J! 2.5.9) that you can use to restore your site before all these problems began?

I apologize for not responding to your previous post.

Yes, I do have backup, but only the backup while site was on J!2.5.9 before J update to 2.5.17.

I did the J update to 2.5.17 after you advised, since the 2.5.9 was not supported.

The update to Kunena 3.0.4 was done prior to Joomla update.

That may be the problem now. Not sure.

I did the debug mode, but i received error 500 on the page, instead on the footer.

Not pointing to any Kunena error.

The site otherwise works without any problems.

Debug mode is killing all my pages - have to remove the call.
See the included screenshot while in debug mode for forum page

Thank you for your reply; we may be getting somewhere.

The information shown when you run Joomla debug mode tells us a few things. The first thing it tells us is that the error message concerns (at least one of) the Joomla database tables: the table _categories. This is the table that deals with Joomla articles - it has nothing to do with Kunena.

The second thing is that you have set MySQLi as the database type in your Joomla global settings. While it may be possible to run Joomla with MySQLi instead of using MySQL - I cannot tell you more about this because I do not use MySQLi on any of my sites - Kunena is optimised to run with MySQL. As a suggestion, try changing to Global Configuration » Server » Database Settings » Database Type = Mysql.

Try this first and see if it makes a difference.

My suspicions remain that your Joomla database tables (one or more of them) are corrupted, possibly because you have not kept your Joomla software up-to-date - you were using a version of J! 2.5 that was superseded in May 2013 - or possibly because there was an issue that has been dormant (and unnoticed by you) until you enabled Joomla debug mode.
