Nick:
Wow, that is a strange error. Did you overwrite the files that needed overwriting, including the communityserver.config file.
Sounds like the db is missing some permissions, I would post this over at http://dev.communityserver.com
Thank you for your reply,
I overwrite all files and try two method of upgrade but the same error still occurs. Now I can't write blog post because when I click on New Blog post this error happen. However I can still post new media and forum post although I see the error but the post still updated.
I have posted this to CS.org but there no solution for the time being.
I ask you because I think you successfully fix this error for you site.
Thank you,
