The mod PBB in the common.php calls a function from the XoopsDatabaseFactory called get() in an attempt to retrieve the db name. When the function name is infact getDatabase() once I corrected that error I proceded to the next which then I found quite confusing as you added at one point to a variable called $sql and it didn't have a "pre-determined" value using the append statement '.=' that I don't think was the cause of the Invalid Mysql-Link reference on line 236 in mysqldatabase.php.

Any help is welcome.

I concure. Same Problem.
