Bell notifications is not working for alll users
The notifications are zero to many members and they are complaining to me, in some members notifications are working fine, i logged with their accounts and checked
I think the notification bell is used in no-forum pages, and they are cached by WP Optimize page cache plugin. It works fine on forum pages because you've excluded the forum page from WP Optimize page cache plugin.
So, if you have a cache plugin you should not display the notification bell on non-forum pages. I think you use the notification widget in other pages.
i dont use any optimize plugin , and i am talking about forum pages absolutely.
