Basic Trouble Shooting:
1. Identifying whether you have a theme issue:
⇒I tried other two themes[ Onepress and Twenty Twenty-One],
but the icon[×] trouble occurred in buddypress profile page.(Nothing happens)
2. Plugins:
⇒In the bbpress is activated only, the icon[×] works completely.(The topic deleted!!)
In the bbpress and buddypress set, the icon[×] trouble occurred in buddypress profile page.(Nothing happens)
Both test, the other plugins are invalid(not active).
3. BP Themes:
Both Buddypress Nouveau and Legacy, same wrong display.(Nothing happens)
I think it is something wrong with the icon[×] button? on forum section in buddypress.
Nothing happens when that [x] is clicked.
