Hi,
I'm trying to move our company's site to Linode, but preparing the migration, I encountered the following problem:
I have nginx and php-fpm installed and configured along with phpmyadmin.
When attempting to create a user with phpmyadmin, I get these errors:

#1065 - Query was empty

The selected user was not found in the privilege table.

This has been blocking me from migrating for a week now both on my personal site, and my company's one, so I would really appreciate some help.
My phpmyadmin version is 4.5.0.2
Thanks in advance!

I'm Hungarian, so please excuse me for grammatical mistakes

It's tough to tell without getting some hands on with it. What user are you logged in with in phpmyadmin? Make sure the user you're using has appropriate permissions to run the queries you're trying to run.
