upgrade to version 22 module error
Roll Groups Error Module error due to incorrect manifest file or folder name.
Anyone having this issue?
This is a legacy of some nomenclature changes in v22, in which we finally changed all instances of roll group in the code base to form group. This brings more consistency across the system in an area of long standing ambiguity.
All you need to do is remove the /modules/Roll Groups folder from your Gibbon installation. Reloading Admin > System > Manage Modules should show that the error has disappeared.
