I found a MediaWiki extension named Extension:Recent_Changes_Cleanup. This extension does not work with MediaWiki 1.27 and larger.
It only works with 1.23.x - 1.26.x
I search the Official MediaWiki website for MediaWiki Version 1.25.1
I installed the download into a in a sub folder that i named cleanup.
I connected my database to the MediaWiki Version 1.25.1. I installed the extension and now i can cleanup recent changes page. To see a working example visithttps://www.jehovahsays.net/cleanup/wiki/index.php?title=Special:RecentChangesCleanup
