"Logging out" of phpMyAdmin?

The error that I get on phpMyAdmin is the following

The phpMyAdmin configuration storage is not completely configured, some extended features have been deactivated." 

I have googled and looked this up for a while now and the common answer that comes up is to Log Out/In or the clear the cookies and cache. Clearing the cookies and caches did not work for me. I have tried to logout, but cannot seem to be able to find out how to, because in the updated version of phpMyAdmin, I believe that there is no logout button as opposed to the older versions which is why people posted that as a solution before. I am not sure what version of phpMyAdmin I have because I downloaded it through xampp, but this is what mine looks like:

click on this button out your phpAdmin home page

As said here and i quote:

just change this line on config.inc.php

$cfg['Servers'][$i]['auth_type'] = 'config'; 

to

$cfg['Servers'][$i]['auth_type'] = 'cookie'; 

then you will be prompted to login when you refreshed the page. Afterwards, the log out icon will appear next to home icon.

The second button from the left. The one on the right of the house in the image you posted is your logout button.

For your error message try this link in the documentation: http://wiki.phpmyadmin.net/pma/Configuration_storage

Make certain you have a phpadmin control user account created. This is covered in the second paragraph in on the documentation page in the link.

In one click

Logout from PhpMyAdmin with URL like /phpmyadmin/index.php?old_usr=xy

EDIT: It works with PhpMyAdmin version 4.0.10.18?

The presence of the logout button depends on whether you are required to login or not, in the first place. This is tweakable in PHPMyAdmin config files.

Yet, I don't think that would change anything concerning your error message. You would need to fix the configuration for the message to go away.

Edit: this is the kind of solution you should be searching for. And here are plenty of others for you to explore ^^
