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

[thoand]

Hi there,

I had a long night yesterday and during this I totaly broke my system.
Ok most things are working, but not the mainpage...

What I did:

1. I updatet my Debian etch, no problem
2. I updatet my ispCP from 1.0.0rc2 to 1.0.0, ispCP works fine, but I have problems with joomla now. It tells me that I do not have "mysql_connect()". php5-mysql is installed.
3. I thought it might help to update to 1.0.5 so I did, but it did not help.
4. I found out that fcgid makes problems in etch, so I tried to get back to fastCGI, did not work
5. I fully Upgraded my Debian etch to lenny and rerun the isp-update, ispCP, Mail and co works, but joomla tells me that there is no mysql_connect().
6. I tried a bit with fastcgi vs. fcgid, but nothing helped.

What surprises me, I edited /var/www/fcgi/DOMAIN/php/php.ini to allow phpinfo(); but even after a restart of apache it told me, that it is forbidden.

Any suggestions?
kind regards,
thoand

PS: the Joomla error I get is Error 1 http://forum.joomla.org/viewtopic.php?t=3647
