I've clobbered my installation - not yet online with users - as follows: Lost password for Mysql DB for Sitebuilder. Restored wrong password - thus not fixing the problem and clobbering password for admin - from Plesk 7.5.4 -- So - couldn't get back into admin on plesk. SO - getting very tired and frustrated, rather than just stop, sleep on it and fix it in the morning, I attempted to a) delete and uninstall all rpms for both packages, then reinstall... Well - with no proper users in Mysql - plesk couldn't install - so I finally fixed that, then, on the last try - the message 'cannot determine version information' comes up on psa_installer after first screen. SO - now what? Does anyone know what to do, short of reinstalling linux from scratch and totally starting over? Thanx!
