I setup BP last week and activated the Network. Seemed to be working fine. But today I received “Fatal error: Call to undefined function add_contextual_help() in /xxxx/cccc/public_html/xxxx/wp-admin/network/settings.php on line 22” when I attempt to access the Network. Now I’m effectively blocked out. I thought it might be a plugin problem, but when using FTP to remove/check/replace plugins the problem still exist. What exactly does this message mean and how can it be resolved? Thanks.

Call to undefined function sometimes means an incomplete upload/upgrade or could be caused by some outdated themes.
– Manually re-upload WP and BP files via FTP/cpanel then change theme to WP default theme.
– Activate BP plugin and bp-default theme first, then the rest of the plugins. See at which point you get an error,
