phpMyAdmin: MySQL: Error #2002 - Can’t connect to server

Hi!

I’m trying to test a wordpress-blog on my local machine (iMac). Everytime I run phpMyAdmin the above error message is being displayed. MySQL-server is running (show by the mySQL-control-panel in the system-preferences). I’m looking forward to any help!!!

Thanks,
Karsten
