Issue:
Been running BuddyPress a few years on this site. Suddenly an issue when trying to create a new BP group – it just goes to the first screen (Details), I enter Group name and description, and when I click “Create group and continue” it just clears the form. This is a membership site, so you would need to be logged in to see the Groups page.

Error log shows these errors:
#3 /home/novelnetwork/public_html/wp-content/plugins/buddypress/class-buddypress.php(522): require(‘/home/novelnetw…’)
#4 /home/novelnetwork/public_html/wp-content/plugins/buddypress/class-buddypress.php(125): BuddyPress->includes()
#5 /home/novelnetwork/public_html/wp-content/plugins/buddypress/bp-loader.php(46): BuddyPress::instance()
#6 /home/novelnetwork/public_html/wp-content/plugins/buddypress/bp-loader.php(90): buddypress()
#7 /home/novelnetwork/public_html/wp-settings. in /home/novelnetwork/public_html/wp-content/plugins/buddypress/cli/src/scaffold.php on line 19

Any help would be appreciated!
