Plugin conflict with Groups

Hello, there seems to be a conflict with the Groups plugin. When activated, I can’t see a BuddyPress group page created with BuddyPress Group Extras. When I deactivate it, I can see the page. Here is the error I get when I turn on debug:

Strict Standards: Declaration of BPGE::display() should be compatible with BP_Group_Extension::display($group_id = NULL) in /home1/nigelyos/public_html/rhs/wp-content/plugins/buddypress-groups-extras/core/loader.php on line 1113
