not creating pages properly and error report

I set up a new buddy press site, but get this error report when I set it up, the pages do not seem to be created properly.

Warning: Illegal offset type in /home/eiqhazns/public_html/theonlinejvclub.com/wp-content/plugins/buddypress/bp-core/admin/bp-core-update.php on line 642

thanks
