 I encountered an error message when publishing or updating. Due to a
 mistake in a wrong sentence, the error message appears. You will get the
 error message "Updating failed. The response is not a valid JSON
 response". Why did it happen?

 - WordPress 6.4.3 running theme GeneratePress.
 - .htaccess file according to wp settings
 - Permalinks postname settings
 - Already started with HTTPS
 - REST API no 404 error message
