no mySQL access via Joomla after update from 1.0.0rc2 to 1.0.0 to 1.0.5

Hi,

I purged it before, but tried it again. But after installing it again it did not work.
To be sure I restarted apache.

Am I wrong that ispCP uses php5-mysql? If not it could not be a general installation problem, because ispCP works fine. It has to be some configuration problem. But php tells me that it has loaded the file /etc/php5/cgi/conf.d/mysql.ini in which is defined that php should load mysql.so.
So what domain specific configuration could be the problem. (I even switcht the support for php and cgi in ispCP for the domain from on to off to on. It did not help)

PS: the problem occures on all three hosted domains (configured as separate customers)
