So I tried the BP Classic Plugin and no changes. Did a bunch of testing and IF a notification has NOT been read or dismissed for ANY user, they can see the normal front end of the Website fine/all works as before. HOWEVER if any user dismisses or deletes any notification then they get a blank web page with just our header and the BP Icons, with no console errors etc.
So having a Notification or NOT having a notification is the trigger for the Theme failing.
Installing BP Classic made not change.
That said, I am likely not understanding the thread you provided or how the update worked. Rolled to 11.4 all well again. Appreciate the support, and a fantastic plugin.
Hello @imath – After 12.0 update if the “Notifications” Setting is set, it appears to take over/override my theme. (Reign Theme + Child Ultimate Buddy Press Theme) NON Admin users cannot see the site as some kind of code overrides the Theme.
Let me know if I can provide any details.
(Rollback to 11.4 is great, or DISABLE 12.0 “Notifications”)
