We know the problem of users whose website is hosted by Host Europe.
Please send us an email to firstname.lastname@example.org. In this mail please give us your username and the exact address under which your (not working) web integration is located, e.g. www.mypage.de/clients. We will immediately send you a customized web integration that should fix all problems.
All you need to do is unpack this new web integration to your hard disk and select the folder contained in the FTP program as a whole, upload it and overwrite the old folder on your server.
