Nothing happens when logout button clicked

Hi there

I've installed the logout button plugin on a 3.7.2 site and have used the example from the documentation to add the following button to the site:

However, when I click on it nothing happens. I don't see any script errors in Chrome Inspector either and I've already tried removing the other classes in case they were interfering, in addition to originally have it as an <a> link instead.

Any ideas what might be going on?

Sorry, my bad, the plugin actually works fine - the issue was actually another module which had been set to only be displayed to non-logged in users wasn't working properly so it was misleading me into thinking I hadn't been logged out.
