Thank you for responding. I would greatly appreciate if you could give me a bit more help.
I have a rudimentary understanding of rpm, but I don't know how I get the package from your site and I don't know how to install it on my server. Could you elaborate on the process?
Just out of curiosity, what about MySQL 5 causes psa to break?
Plesk 8 is having the feature to allow multiple mysql servers. Isn't it possible to run two mysql servers on one system? Than you can have a standard mysql4 server and the extra mysql5 server on a different port.
Idea?
