Thread:Extension talk:UserAdmin/Works with 1.19 (modified)/reply (3)

I tried to add this to a fresh 1.19.1 install, and when I went to "Add User" in the Special:Pages, I got this error: Fatal error: Call to private method User::loadGroups from context 'SpecialUADMBase' in /home/myusername/public_html/wiki/extensions/UserAdmin/SpecialUADMBase.class.php on line 530

Which references:    $user->loadGroups;

Any help?
