Hi Rikard,
Thanks for the response. The issue was present on all admin pages utilizing TinyMCE. I had previously tried deactivating all plug-ins when I opened my original issue for the “hang on loading spinner”. I hadn’t tried this troubleshooting technique for the TinyMCE issue. I pinpointed the issue to the Uptime Robot Plugin for WordPress. Thanks for your assistance. You may close this issue.
After further investigation, I found the error:
Uncaught Error: cannot call methods on sortable prior to initialization; attempted to call method ‘toArray’
Further research lead me to this thread. The posted solution didn’t work for me. I then found this thread. This solution did work for me, temporarily.
