I have updated my oxwall cms and i try to update FBconnect, the message of "update plugin database" block my admin area, but when i click on, a MYSQL [23000] 1048 Error stop me.

Can anyone help me to solve this issue?

I have attach an image of owdebux exception, type PDOException.

From the owdebug seems like a problem of language files, but i'm not so expert, sorry if i'm wrong. I need to fix this ;-)
