Some users reported that they have problems to login to this site and post something at the forum. If you have these problems, it might be helpful if you access this site by its IP address, which is http://62.148.162.119. Someone else reported that it helped, loggin in here with Internet Explorer, if you switch the Security Level to "low", so that IE accepts the cookies from here.
At the Demo site it's the same issue. If you have problems loggin in there, go to http://62.148.162.119/demoshop and try again.
Thanks.
