   I can’t upload media too. The error, “Updating failed. The response is not a 
   valid JSON response.”

 * Hello [@trendbaze](https://wordpress.org/support/users/trendbaze/),
 * I’m sorry about the error you encountered. Often, we see problems occur in combination
   with another plugin or theme. The fastest way to rule out any conflict is to **
   deactivate all non-Yoast plugins and switch to a standard theme** like [Twenty Twenty-Two](https://wordpress.org/themes/twentytwentytwo/).
 * Please test this on your development or staging site if you have one. If not,
   we recommend using the [Health Check & Troubleshooting](https://wordpress.org/plugins/health-check/)
   plugin. This plugin has a troubleshooting mode, which **does not affect normal
   visitors to your site**.
 * If you’re unfamiliar with checking for conflicts, we’d like to point you to a
   step-by-step guide that will walk you through the process: [How to check for plugin conflicts](https://yoast.com/help/how-to-check-for-plugin-conflicts/)
 * If you feel uncomfortable doing this yourself or if this does not solve your 
   issue, our [Yoast SEO Premium plugin](https://yoast.com/wordpress/plugins/seo/)
   comes with one year of (technical) support.
