Hello, I have recently migrated a wordpress website from one server another. I archived the files, sent them to the new server, unarchived them, dumped the database, sent that to the other server (and configured db user etc.). Then I created an ssl certificate, copied the nginx config over and the website seemed to be working.
However, today I tried to edit a page but the page is just white. It does show [these errors]) for a split second.
Looking at the error logs there are just a bunch of deprecation errors and this warning: `PHP Warning Undefined variable $checkout in /var/www/wordpress/wp-admin/includes/class-wp-automatic-updater.php on line 175` that I don’t think has anything to do with the problem.
Would be awesome if someone had an idea what this could be.

Did you backup and restore any custom css? Probably that’s the problem of blank page.
And check the PHP version, make sure its the same version of the old server.
Every time if migration fails. One reason: Different PHP version in between.
A deprecation warning is just a warning. It won’t affect the site negatively, but it will in future versions of php. Is there a fatal error? If not, just disable debugging.
