I have pro version of DNN (Evoq) 7.2

I have many portals divided up into many site groups. In some site groups I go to add an existing module and it will pull up a list of the portals in the group but I can not open the site item to list pages to pick an existing module to add.  Other groups it works fine - just as expected.

I have seen a few forum items where it mentions Newton JSON may have the wrong version but that seems to be okay.

Any other things to check?
