I have this plugins to update
Admin Bar – You have version 1.3 installed. Update to 1.3.1. Requires SP Version 5.2.
Editor TinyMCE Rich Text – You have version 2.0.1 installed. Update to 2.0.3. Requires SP Version 5.2.
Private Message System – You have version 1.5 installed. Update to 1.5.2. Requires SP Version 5.2.1.
Subscriptions – You have version 1.2 installed. Update to 1.2.2. Requires SP Version 5.2.
But when I try to update them it says they’re already updated
Also, when I was upgrading to SP 5.2 it said I should empty the cache, but when I clicked the button it said I had no permissions
