Signup problem in haddock

I am trying to signup in HADDOCK server but it showing error “You did not submit a valid signup form. Please check the required fields”. I can not understand why. I have filled all the required fields. I put the Research Institute Web address (URL): www.pku.edu.cn/
Please suggest what to do for signup.

Did you try other web browsers?

I am trying using google crome browser.

I am facing the same problem using mozilla firefox

Do you see a box to check stating that you are not a robot?
Somewhere at the bottom of the page?

Send me offline (i.e. direct email) a screenshot of what you are exactly filling.
