You granted the user permissions only to the ‘charmstyle_com’ table inside the ‘charmstyle_com’ database. What you probably want is to grant permissions to all the tables in ‘charmstyle_com’ (or at least the ‘adminnotification_inbox’ table)
GRANT ALL PRIVILEGES ON `charmstyle_com`.* TO 'charm'@'localhost'
alternatively
GRANT ALL PRIVILEGES ON `charmstyle_com`.`adminnotification_inbox`
TO 'charm'@'localhost'
