I have installed the latest Activity Feed solution (from UR12) for On Premise.
Two entities enabled and can post to their record walls.
I can open an entity form and use the FOLLOW button successfully.
However the ribbon buttons do not enable when I select rows in the grid view for those entities.
All I can see that might be wrong is the Developer Resources REST url for OrganizationData.svc fails (discovery does return the xml)
Could this be the issue and if so how do I fix it.
