Hello,
I reviewed all of the posts with similar issues.
Issue: The website looks just like it did from X. Cornerstone is disabled (automatically) & when I attempt to edit anything with pro (headers, footers, content, etc), It just continues spinning.
What I have attempted:
- Confirmed PHP version (7.2)
- Updated links (changed htaccess & saved in perma-links)
- Cleared site & browser cache
- Disabled ALLLLLLLL plugins
- Increased memory limits
If I switch back to X & enable cornerstone, it works without any issues. If I switch to Pro, I am unable to “edit with pro”.
Am I missing anything?
