e-mail not valid in comments

First: Writing English is not what i do best. Sorry.

Second: There is something wrong with my comment settings (?). I want my readers to leave name and e-mail in comments. But the lines seem to be messed up. The middle line (name) doesn’t work at all. And no matter what e-mail adress my readers try to use, wordpress says it’s not valid. So i went to my CP and removed the “Need to leave name and e-mail”, and now everybody ends up being anonymous when they write name in the middel line (line for name). What’s up with this?
