I face the same problem too, I’m using Avada theme and Fusion Page builder, after update can’t edit my page and post. Clicking the SEO field nothing happen, a weird icon show beside the move to trash link, and the “We’ve updated our SEO score algorithm. Click here to recalculate the SEO scores for all posts and pages.” keep showing even after recalculate.
For now have to deactivate first.
How to revert to old version?
TQ
