Cannot logout of admin interface – TML!

Hi

I use the TML widget on a few sites, but with the 2 latest, after working well for a while, a problem came up a few days ago, where I could not log out of one – with not found page with link “/logout/?_wpnonce=6b0bb3426b”.

Today, this is happening to the second site.

What is going on?

I have searched and found people mentioning the same problem, but I do not see any solution which works, other than disabling the plugin.

I have been doing normal updates on the site – like customizing the theme or working on content & with one site, disabling all other plugins, & changing from the currently used twentyfourteen theme, leads to no change.

I would appreciate some urgent help.

Kind regards
