Hello,

I use your plugin for many years now and on many of my sites and is a great plugin, but this last update is not working like it sholud. I updated from 4.1.4. to 4.1.7.
The css styles changed, that is not a big problem but in the backend the when I try to costumize the menu the screen is all messed up.
And it sais UNAUTHORIZATED – This serves could not verify that you are authorizated to access the document requested. Either you supplied wrongcredentials (e.g., bad pasword) or your browser doesn`t understand how to supply the credentials required.
