Https access authentication workd but not normal

I tried to use a simply link to login in the basic access auth: http://ift.tt/2vrENYx. In Forefox it's working really good. But in other browsers like Chrome it loggs in but first the browser displays only the website structure. When I load the one more (STRG + F5) all is displayed as wanted...

Does anybody know why and how to solve this problem?

Sorry for my bad english...

Thank you very much!
