When I try to load Special:SpecialPages locally, I get several warnings including:
Strict standards: Declaration of SpecialGlobalGroupMembership::fetchUser() should be compatible with UserrightsPage::fetchUser($username, $writing = true) in /Users/kaldari/Sites/core/extensions/CentralAuth/includes/specials/SpecialGlobalGroupMembership.php on line 137 Warning: Cannot modify header information - headers already sent by (output started at /Users/kaldari/Sites/core/includes/AutoLoader.php:81) in /Users/kaldari/Sites/core/includes/WebResponse.php on line 45
If I disable CentralAuth, the warnings go away. I'm using the latest master of both core (fb2eaec) and CentralAuth (60a9fb8).
