ok I didn’t want to switch themes on the live site so I have a locally hosted dev site configured the same but without all the content. Way fewer tags and categories. It works fine with 2016.
on the live site the widgets page is now working although it’s really slow. I guess we’re just going to have to put up with it.
I think I should talk to the editors about decreasing the number of tags. We have over 21,000!
Thanks
