Hello! Thanks for a useful extension, however, I got a little annoying bug, while using it on my Mediawiki 1.4. I get this message when I tired to delete a page:
Deprecated: Use of wfGetDB was deprecated in MediaWiki 1.39. [Called from ActionDeletePagePermanently::deletePermanently in /.../extensions/DeletePagesForGood/ActionDeletePagePermanently.php at line 92] in /.../includes/debug/MWDebug.php on line 379
