Thread:Extension talk:UserAdmin/PHP Fatal error: Call to private method User::loadGroups() from context 'SpecialUADMBase'/reply

Replacing loadGroups with public getGroups (which calls loadGroups ) in all instances of UserAdmin will make the error go away...

On using Special:UserAdmin with MW18.2 I'm now getting heaps of warnings like:
 * Warning: array_merge [function.array-merge]: Argument #1 is not an array in /MYURL/public_html/wiki/includes/User.php on line 2295
 * Warning: array_unique [function.array-unique]: The argument should be an array in /MYURL/public_html/wiki/includes/User.php on line 2295
 * Warning: array_diff [function.array-diff]: Argument #1 is not an array in /MYURL/public_html/wiki/extensions/UserAdmin/SpecialUserAdminPanel.class.php on line 395
 * Warning: Invalid argument supplied for foreach in /MYURL/public_html/wiki/extensions/UserAdmin/SpecialUserAdminPanel.class.php on line 397


 * Disabling warning display will get rid of them.
 * errors do not show up on MW19.0beta2 however... - Arent (talk) 10:39, 13 April 2012 (UTC)
