Control panel > database tools > info
/admin/dbinfo.php
SHOW TABLE STATUS LIKE '{$config['TABLE_PREFIX']}%'
This query does not escape special characters, like the underscore.
I have both an ubbtest_ and ubbt_, and if I do a database info on the ubbt_ setup, I also get all ubbtest_ tables. Escaping the underscore with an \ would do the trick.
Not really a biggy I guess
