Thread:Project:Support desk/My MediaWiki isn't working because of an Database error

My Wiki was working for a while and now it has stopped working. What I mean by stopped working is I can't create new pages. I haven't made an changes apart from uploading some extensions. I also tried removing them and that didn't seam to work either.

A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was: (SQL query hidden) from within function "efUpdateCheckUserData". Database returned error "1146: Table 'systemc4_beta.betawiki_cu_changes' doesn't exist (localhost)".

I done a fresh install on a different URL and it still didn't work.
