 * This is brilliant and it saves 2 of my site from page builder (like Elementor).
   Actually i used it for homepage design only.
 * However, when Im using it 3rd time on my another site it gives me an error. Its
   call “Updating failed. The response is not a valid JSON response.” while I’m 
   update/creating any page with it.

 * I know there might be another reason for this error but in this case the “plugin”
   is the culprit.
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fnot-a-valid-json-error%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hello [@mtshawn](https://wordpress.org/support/users/mtshawn/) ,
    It causes by
   any syntax error inside a action hook, which is related to the save action. You
   can follow this steps:- Try deactivating all the plugins and see if the problems
   persist. If the issue is no longer there, then activate the plugins one by one
   to see which plugin is causing the issue. If you find an issue with a 3rd Party
   Plugin, reach out to the developers of the 3rd party plugin.
 * Please follow this guide-

 * Thanks man, for quick response. And i just figured it out. In my case your plugin
   conflict with my “light speed cache” plugin. I just remove cache plugin and it
   works as usual. #Thanks.
