This has been achieved thanks a lot!! But I have 2 servers which show the following under "Home>cPanel>Manage Plugins" in the Munin plugin:
Name: munin
Author: cPanel Inc.
Version: obsolete
Description: Munin Server Monitor
Price: free
If I install it it will install 1.4
I have ran "Software>Rebuild RPM Database", "Software>System Updates" and "Software>Update Server Software" Without any luck...
