Is the group page assigned to groups component in BP settings ?
Does your DB contain the 3 tables related to groups ? (_bp_groups, _bp_groups_groupmeta & _bp_groups_group_members ?
Have you tried to use the BuddyPress repair tool ? Dashboard > Tools > BuddyPress ?
Yes, I’ve checked all these things and they’re accurate.
Did you restored your DB before WP was updated to 4.3 ?
I actually did not need to restore my database, just the site files. And before WordPress upgraded to 4.3 it prompted me to upgrade the database which I did.
(Thanks for all your help, by the way.)
The solution in that other topic worked for me! Thanks so much for sharing that 🙂
To all readers, Codex reminder when getting 404, missing BP pages, not found errors after setup or upgrade ! 😉
Settings → BuddyPress → Pages
Pages are automatically generated for the BuddyPress components you enabled in the components settings using the default slugs based on the name of each component activated. Make sure that activated components have corresponding pages assigned to each in this panel.
Directories
Associate a WordPress Page with each BuddyPress component directory.
- Activity Streams (if activated)
- User Groups (if activated)
- Members > this is core and can’t be removed/modified
Registration
Associate WordPress Pages with the following BuddyPress Registration pages.
Note: registration is not a BuddyPress component but part of WP core.
When you allow user registration, you have to add manually these pages.
