Thread:Project:Support desk/new database table? but how

Hi, i have a problem with instaling extension Approved Revs. After editing LocalSetings.php, it showed me this:

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 "DatabaseBase::selectField". Database returned error "1114:Table 'mywiki.approved_revs' doesn't exist (localhost))"

I think that problem is in part of the instalation, that says "You will also need to install a database table for this extension, also called "approved_revs".", but i have no idea what to do :-(. Can anyone help?

thx
