Thread:Extension talk:FlaggedRevs/Error in contribs

Hi, after I installed the FlaggedRevs extension, the following PHP warning turned up in the contribs page. Warning: Missing argument 4 for FlaggedRevsUIHooks::addToContribsLine in path/to/wiki/extensions/FlaggedRevs/frontend/FlaggedRevsUI.hooks.php on line 495 Warning: Cannot modify header information - headers already sent by (output started at path/to/wiki/extensions/FlaggedRevs/frontend/FlaggedRevsUI.hooks.php:495) in path/to/wiki/includes/WebResponse.php on line 38

The first line repeats for every edit shown in the contribs page. Could anybody help me with this? Thanks!
