– By ‘save’, you mean update?
Yes, sorry for my english
– Have you tried editing and updating any other emails?
– If so, did the same issue occur?
Yes. If we update any mail, the mail are saved as post type, not as BuddyPress Emails type (bp-email type).
– Have you tried using the Email Repair tool?
– wp-admin > Tools > BuddyPress > ‘Reinstall emails (delete and restore from defaults).’
This will delete your current emails including any edits you made to them.
“Reinstall emails” work fine but the problem is the same: all new mails are not updatable.
– What version of WP are you using?
We use WordPress 4.4.2.
