Security

Hi, I get some strange messages when trying to log into Che55.com. Firefox claims the security certificate is untrusted and asks me to put an exception. This is the only site where such a thing happens, secured or not. Does it happen to anyone else? Is there any way to repare it without having to put an exception? Would really love to see such security issues away.

Any admin there? I don't know if the answer to those questions is trivial, but i don't find it a leger thing, even considering leaving for the sake of internet security.
