I just read about this this morning. I have a vanilla wordpress them site but also support a legacy client’s site that is
wordpress
a studiopress theme AGENCY
while using Elementor within that.
Sounds like Gutenberg is a replacement for Elementor at least. Have no idea what evil it will do with studiopress themes. MAybe that’s why they sold to the new company.
I also have have custom pages that use query args that embed posts by categories in order. What the heck will happen to those pages in Gutenberg?
Goggle analyticator was the culprit it’s newest rev 654 when deactivated all problems went away
