BuddyPress.org

Hello, I just installed BuddyPress and bbpress on my site which is running pitch theme. everything is running well. but I did find a warning message when I click on “members” under Groups / Group one >Members.
1) Groups is buddypress group.
2) Group one is the sub group that I created under buddypress group
3) members is one menu under “Group one”.
here is an error message:
“Warning: Parameter 1 to CustomHeadersAndFooters::loop_start() expected to be a reference, value given in C:\xampp\htdocs\wordpress101\wp-includes\plugin.php on line 429”.

please help!
