The Manual tells: "After you have received your user name and password and the url of the ISPConfig system from your reseller you can login. Please go to the URL of the ISPConfig system (e.g. https://www.domain.tld:81 ; "www.domain.tld" has to be replaced appropriately) with your browser and enter your user name and password in the form "Login". Confirm by clicking on "Login". " If our customer enters https://www.customer-domain.de:81 he has acces to ISPConfig. Everything looks fine but if he uses one of the Context-Sensitive-Help-Buttons" for example the "i" after the Hostname a Pop-Up open with our Domain in the Header and a Login-Screen. Is there Anything i had configured wrong?
These File is set to https://www.our-domain.de:81 those these mean our customer can only log in through https://www.our-domain.de:81 and not through https://www.customer-domain.de:81 ?

This does not fix the Problem. :-( After this change some Images in the ControlPanel are broken and after a klick on an Context-Sensitive-Help-Buttons you get a Page not Found Error.
