Hi,

I want to upgrade to plesk 8.0 but I had this error:

Resolve components
ERROR: Impossible do installation while package mysql-4.1.11-2.i386 is installed in system

Could you please help me to upgrade my plesk with the same version of MySQL that I installed. Some application of my clients, need version upper than 4.

Regards,
