 * Hi,
 * I am currently building a child theme on GeneratePress. I have an image upload
   control that updates the GP color palette when the control is changed.
    The JavaScript
   Customizer API is triggered when the image is uploaded. I use JS to extract colors
   from the image to create a custom color palette. Then I send the custom palette
   to WordPress using a REST API. The GP settings get changed on a GP hook, which
   runs when the controls are updated in the Customizer and on page loads.
 * My issue is that after changing and saving the Customizer settings then exiting
   the Customizer and viewing the page, I see a `customize_changeset_uuid` parameter
   in the URL while I’m viewing my website. When I go back to the Customizer through
   the button on the admin toolbar, [I get the “this changeset cannot be further modified” error](https://ibb.co/DCZjPJy).
   
   I am totally stumped about this and I am having trouble finding resources on 
   the internet relating to my issue. Am I saving theme settings incorrectly? Some
   help and guidance would be much appreciated, thanks in advance!

 * This may be a plugin or theme conflict. Please attempt to disable all plugins,
   and use one of the default (Twenty*) themes. If the problem goes away, enable
   them one by one to identify the source of your troubles.
 * _______
 * If you can install plugins, install and activate “Health Check”: [https://wordpress.org/plugins/health-check/](https://wordpress.org/plugins/health-check/)
   
   It will add some additional features under the menu item under Tools > Site Health.
   On its troubleshooting tab, you can Enable Troubleshooting Mode. This will disable
   all plugins, switch to a standard WordPress theme (if available), allow you to
   turn your plugins on and off and switch between themes, **without affecting normal
   visitors to your site**. This allows you to test for various compatibility issues.
   There’s a more detailed description about how to use the Health Check plugin 
   and its Troubleshooting Mode at [https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/](https://make.wordpress.org/support/handbook/appendix/troubleshooting-using-the-health-check/)
