Question Wrong Database Version but Still Working

Hi,

I recently installed Kunena on Joomla which is currently using a pre v5 database but with php 5.0 I had the install error warning (about php5 which is strange as well), and have the error:
However the forum works fine and the error only appears in admin.

Would it be ok to continue to use the forum or is this a serious problem?

Any help appreciated.

Thanks

This is actually a bug which has been fixed..

But seriously: there are two different kind of problem with old MySQL releases:
1) they are really slow on Kunena
2) Many of Kunena SQL queries do not work with MySQL <4.3 and there may be some that do not work well <5.0

Thanks for the information.

The thing is I've been testing the forum and it seems to be pretty quick and works fine; the database info is from an old fireboard installation but apart from the admin error everything is working. I just don't want to put this to production then it breaks. It looks v stable at the moment, I know you said some queries won't work but I have tried everything to break the forum and it is fine.

The reason I want to use Kunena is that it integrates with Jomsocial for the avatar. Updating the database I think will not be possible at the moment any suggestions welcome.

Thanks

Many of our queries use subqueries to do the task:

SELECT * FROM (SELECT s1 FROM t1) AS x;

Those are very slow (not optimized) in MySQL <5.0. You cannot see the difference on small forum, but large forums can be really slow.

Actually I cannot find any new feature in MySQL 5.0 that we use. So Kunena may actually work on MySQL 4.3+. Older MySQL versions do not support subqueries and they are used to fetch messages, so.. Don't try Kunena with them.
