Thread:Project:Support desk/Upgraded php version to 5.3.3, and mediawiki 1.10.0 stopped working

Is there a safe way to get Media Wiki up and running again with my new version of php(5.3.3)/mysql? I would really like to retain all my information, and would ideally prefer to avoid a complete reinstall if possible.

Or if i must reinstall, is there an easy process to avoid downtime?

Thanks in advance for any help!
