Thread:Project:Support desk/how to Permanently delete a wiki page/reply

The maintenance script deleteArchivedRevisions.php allows you to remove all deleted revisions. Alternatively, the maintenance script nukePage.php allows you to delete selected pages. For this script to work, you will have to undelete the revisions first.

Another possibility - which I prefer - is this: Go to the archive table in your database, choose the revisions, which you do no longer want and delete them from the table. When you are done, run the maintenance script purgeOldText.php in order to remove unused entries from the text table.
