Hi,
Thanks for your query.
Please clear your browser and Joomla cache, and if the problem still persists then please disable mod_security from your cPanel.
I hope this will solve your issue.
Best Regards
Hi,
I have also finding the same problem. And also cleared the browser & joomla cache, but not working.
But I do not know how to disable mod_security from your cPanel.
Is there any other ways to do.
