Hello,
I am having an issue when I try to activate a solution in our SharePoint 2013 site. When I click on it, it will open up a separate window that gives a warning. (See below). Then I click activate and nothing happens, it will stay activated. I've tried different browsers to see if it was that, but no luck. I've looked around for a solution, but all of the solutions are for SharePoint 2013 on premise, but ours is cloud based.
