Customize error: Something went wrong.This changeset cannot be further modified.

Hi team,

When I finished the live-preview and published a customization, the url in address bar will be something like:
https://myblog.example.com/blog/?customize_changeset_uuid=4b375004-617c-47f0-b381-206d12651c4c

In that case, when I hit the “Customize” button again, it will report error:
Something went wrong.
This changeset cannot be further modified.

I encountered the same issue a few months back and I resolved it by completely reinstalling WordPress. This time, I decided not to re-install as I already have quite many posts.

So I troubleshoot it, by inserting some codes in wp-admin/customize.php, and I can see something like this:
——————————————————————————–
$wp_customize->changeset_post_id(): 506
$wp_customize->changeset_uuid(): 4b375004-617c-47f0-b381-206d12651c4c
/***************************************************/
if ( in_array( get_post_status( $changeset_post->ID ), array( ‘publish’, ‘trash’ ), true ) ) {
$changeset_post->ID: 506
get_post_status( $changeset_post->ID ): trash
Something went wrong.
This changeset cannot be further modified.

Customize New Changes
——————————————————————————–

I can not go further hence come here to ask for help.

I am using “Click” theme, not sure if the theme itself is related as I did not try other themes (as I only like this one).

What I have done:
1. I have using some plugins like “Advanced Database Cleaner” or “WordPress Reset” etc to clean up wp_options table, but still have this problem.
2. If I manually changed the url to https://myblog.example.com/blog, and then click “Customize” button, it will work, it seems can not work when customize_changeset_uuid is set on the url.

Pls guide me how can I troubleshoot further.

Thanks,
HoHo
