I’m started with WPMU 2.8.4, FR version, then did the automatic upgrade. I installed Buddypress, the default theme and the parent. When a user tries to activate his account, the go to this sort of URL http://ux-paris.com/wp-activate.php?key=7c9a743c9ff98355 which throws the following error: Fatal error: Call to undefined function bp_page_title() in /home1/thelayen/public_html/uxparis/wp-content/themes/bp-sn-parent/header.php on line 9.
FWIW, in the Buddypress admin panel, it shows that “My current theme is not BP compatible”…but my current them is BP Default?
