1. Mysql installation is correct. All other CMS-Sites can connect to the database.
2. i can connect to the database with the comand-line.
3. the 3 files are correct
4. i regeneratet the password several times... i think it might be correct...

if i connect to the webmailer, i can login. No error. But when i try to connect to pma, i get the error:

Quote:Die Erweiterung mysql kann nicht geladen werden. Bitte überprüfen Sie Ihre PHP-Konfiguration. - Dokumentation

That means, that the extension mysql is not loadet. But i have the extension-part in the php.ini...
