How to change logged Gmail account if the logout button is not opening?

But, just this January 2016, I've encountered a bug (I think) in accessing/adding my other accounts in Gmail while my primary account is logged in.

The error is that the account details/settings is not showing/displaying as I click my account logo.

I thought that my browser (Google Chrome) is just not updated since Auto update is not enabled in my setting. But, as I've installed the updates in my browser, the bug/error is not yet fixed.

I didn't try it in other browsers since Google Chrome is my preferred browser eversince.

I've also asked my friends if they are encountering the same problem with Gmail, and it's working properly on them.

Currently, I still can't find a solution so I decided to just find a temporary way to logout pr access my other Gmail accounts and I'm going to share it in case some of you need it.
