getting fatal error after update thru admin page

[kmtrent]

Fatal error: Call to undefined function bp_displayed_user_id() in /homepages/31/d419853428/htdocs/BHC/wp-content/plugins/buddypress/bp-core/bp-core-template.php on line 1117

Above is the error I received after updating the BuddyPress plugin through my WP admin dashboard. I am now unable to access the WP dashboard, and members on our website are unable to interact.

I was never given the option to access the Update Wizard. When I posted this on the support forum, someone else expressed the same issue. Perhaps it is a problem that needs to be addressed?

Try using FTP and delete older version of buddypress from the plugin directory. Then upload a new version via ftp.
Sometimes this issue may happen when you update via the dashboard as the plugin may not be completely updated.

This is a duplicate of #4403. If you can get a stack trace (using debug_backtrace()) or even just the output of the PHP error log, it would be most helpful. Also, a list of other BP plugins you're using. Thanks.
