    I try to edit (text only) and update. it’s keeps on showing the same error message “Updating failed. ?The response is not a valid JSON response.”

    done the site health check and result is good.

    any solutions?

  • You should be able to see more information in your browser console.

    The most common reason for this though is no permalinks, try going to settings>permalinks and save

    Thank you, Alan Fuller.

    I tried and it’s not working even deactivated theme and plugins. So, I login to cpanel to check the server log and it’s showing 443 error. Then I reported the issue to my hosting service provider and they have rectified and solved the problem. According to the technical support team that the error is caused by ModSec rule blocking the access.
