Config import constantly showing configs to import Recently after doing a config import via drush (drush cim sync), the config files don't seem to import properly, as the files are listed after a supposed successful import.
(and doing a cex sync shows configs to export, despite nothing being changed in the backend)

The only thing I have done recently is import a copy of a database from one of our live test servers, to get the content.

Is there a UUID I need to change or something?
Check that the UUID of the remote and local drupal sites match.

drush config-get "system.site" uuid


You can also get the id from the remote site, by looking into  system.site.yml of your config folder you are trying to import.

To set your local UUID use drush

drush config-set "system.site" uuid "UUID-GOES-HERE"
