Hello Rene,

You should read this post

I did all that, and i keep getting the error....
any advice?

Did this error come out of the blue or did you make changes to any extensions or your db?

If you made some changes and anything went wrong you should restore a working backup.

If not...
Backup again (Never forget this :) ).
Use Admin Tools to repair and optimise your DB.
Reinstall K2 and Joomla! and experiment with the finder plugins.

If nothing works restore a working backup.
