Cache Flush Resets Admin Color Scheme to Classic Dark

[druesome]

Quick summary

Selecting any Admin Color Scheme in Users > Profile (https://mysite.com/wp-admin/profile.php) updates the colors as expected. However, flushing the cache via CLI resets the scheme to Classic Dark.

Steps to reproduce

1. On an Atomic site, click Users > Profile (https://mysite.com/wp-admin/profile.php)
2. Change the Admin Color Scheme to anything other than Classic Dark (preferably something more colorful like Sunrise or Sakura)
3. Press Update Profile
4. Notice the change in colors
5. In a new tab, visit the site's CLI interface at https://mysite.com/_cli
6. Flush the cache with cache flush
7. Go back to the tab containing Users > Profile and refresh the page

What you expected to happen

For the currently selected Admin Color Scheme to stay as is.

What actually happened

The Admin Color Scheme switches to Classic Dark and the colors have changed.

I can confirm that this happens when wp_cache_flush() is called.

It might be related to https://github.com/Automattic/wpcomsh/pull/1669. @Automattic/lego does this sound like something in your domain?

Hi, yep, we can take a look 👍

The issue seems to be gone with the latest WordPress.com Features. Could you help to provide the version of jetpack-mu-wpcom-plugin on client sites? Thank you!

Could you help to provide the version of jetpack-mu-wpcom-plugin on client sites?

I'm not that familiar with Atomic. Could you give me a hint of where to look?

If that helps, the wpcomsh plugin (/home/150760296/wordpress/plugins/wpcomsh) version is 5.8.1-alpha. The atomic site that I'm testing is https://m1r0slav82.wpcomstaging.com.

Here's a step-by-step of how I'm testing this bug:

• Visit https://m1r0slav82.wpcomstaging.com/wp-admin/profile.php
• Change the Admin Color Scheme to something else.
• Go to the CLI and run wp cache flush.
• Go back to https://m1r0slav82.wpcomstaging.com/wp-admin/profile.php and refresh.
• The scheme is reset.

To remove the CLI from the picture, I've also tried executing a file https://m1r0slav82.wpcomstaging.com/flush.php which only calls wp_cache_flush(). The result is the same - the scheme is reset.

I confirmed that the reason is the Admin Interface Style is configured to the Default styles. It means the admin color is based on their WordPress.com account.

I'll continue to check why updating the color scheme from the profile.php doesn't work correctly

Proposing https://github.com/Automattic/jetpack/pull/39368 to resolve this issue.
