#1142 - SELECT command denied to user ''@'localhost' for table 'pma_table_uiprefs'

I stumble upon this issue and I solved it just by logging out of phpMyAdmin and in again.

EXPLANATION
Take a look at the error message query:
SELECT command denied to user ''@'localhost' for table 'pma_table_uiprefs'
This happens due to MySQL denying access to user "" (blank) at server localhost. The default setting is to block all requests from anonymous users.

By logging out we force phpMyAdmin to "forget" the current user and let us input the login credentials for the MySQL server
