I am trying to remove a message regarding buddy list:
Steps I took:
I go to my inbox via the mail icon on the top right
I click the author name to open the mail (inbox.php)
I press delete
I am directed to a page that says, "There are no private messages in this folder." (private.php)
I click the mail icon again, and the message in the inbox is still there (inbox.php)
FWIW, I can delete messages that are in private.php just fine. (This is midly confusing to have two "private message" areas.)
