Check if you installed the lastest version of JCE editor, if you use it already. You need 2.9.41 or 2.9.50 (!)

Hi there,
I appreciate you reaching out. I sincerely apologize for this oversight. Will you please provide me the Joomla administrator access to check the issue? I will check & get back to you soon.
Enable Debug mode and Error Reporting to check if there are any issues.

Thanks a lot. Update JCE Pro was the Solution.
Glad to know that your problem has been solved. :)
