fixing the database worked for me too. It does look like it may be related to the mentioned hack though since one of the listed plugins was a file that seemed to match the description of signs of the hack…
[code]i:1;s:66:"../../wp-content/themes/mandigo1.32/schemes/purple/scheme_old.jpeg";[/code]
The other looked similar to those mentioned above. I removed them both. That deactivated all my plugins, but I reactivated them, and the version number was fixed.
