Hello! I have this error in menu My Accounts of the adminbar:
Warning: Invalid argument supplied for foreach() in /home/xxxxxxxxx/public_html/wp-content/plugins/buddypress/bp-core/bp-core-adminbar.php on line 62 bpress last trunk
What versions of WPMU and BP are you using? How did you install them – upgrade or fresh install? And are you using a custom theme – if you are, does it work if you revert to the standard BP theme (to test)?
