Topic on Extension talk:Access Control Panel/Flow

It's not possible to call Specialpage anymore because of this error. I found a solution here: https://www.mail-archive.com/wikibugs-l@lists.wikimedia.org/msg53602.html. In the file AccessControlPanel.body.php I replaced the lines

       function AccessControlPanel() {
               SpecialPage::SpecialPage( 'AccessControlPanel', 'protect' );
       }

by

       function AccessControlPanel() {
               parent::__construct( 'AccessControlPanel', 'protect' );
       }

as suggested and now it works again. There should be a version control to choose the old behaviour in old mediawikis and change to the new in Mediawiki 1.23

I used it, the same problem in MW1.24. With your suggestion it works. Thank you

Still the same bug in version 1.27. Same here for us. and same solution.

Fixed it for me, MW1.30.0. Thank you.
