Hi, I'm running plesk with 25 wordpress sites on it. And the biggest site is now making problems. Checking the phpmyadmin runtime information suggested me (Watch this picture: http://screencast.com/t/s4y2sIYz4L1 ) to change some mysql variables like tmp_table_size and table_cache.

So I logged in through ssh and changed some variables in the /etc/mysql/my.cnf file and restarted mysql. ( I don't have a /etc/my.cnf file)

So far so good, but as you can see on this picture http://screencast.com/t/Lhs0UlkkjR that the "global" variables are changed but not for my clients site.

Is there a specific configuration file for client databases. I searched now for over 2 hours but did not find a solution.

Thanks, for any help.
