Sorry, this goes much too far.
Our website isn’t political correct so I have to be very careful to whom I give such account details. The login data was a big step to me. But the ftp-data is too much. There are some different domains on the account. I will be in trouble if I give the access data away.
I also do not know why you couldn’t log in with the given details.
So I have to live with the problems. Thanks for your efforts.
