Problem with +FollowSymLinks and phpMyAdmin

[joximu]

Where did you configure the path "/var/www/phpmyadmin/" in apache? or: why don't you use the built in pma?

http://<ispcp-servername>/pma

If you want to use your own pma, then there will be a part somewhere in the apache config where you tell apache to use this folder /var/www/phpmyadmin/ - there is the right place to either set the options directly (instead of in the .htaccess file) or allow setting different options in the .htaccess file: "AllowOverride All" (better: read the apache docu to see what's available)
