I am guessing this has something to do with BuddyPress but I have never seen it before....login and active login is fine...but, logging out I get this error message: Code: Fatal error: Call to a member function getLogoutURL() on a non-object in ****/mywebsite.com/html/wp-content/plugins/amember4/includes/plugin.php on line 56
Seems to be a bug in amember4 plugin which you have installed in wordpress. Try to upgrade it to latest version and if issue still exists please contact us in helpdesk and provide access info, also explain how I can recreate this error.
