plug Signup TOS not working , Show messa You must agree to the Terms of Service in order to signup.

Hi

I install “SIGNUP TOS” plugin,

To registered members page (URL below)

http://rwd-shop.com/pro-site/?action=new_blog

Even if I had agreed to check the terms of service,

Still displays an error message “You must agree to the Terms of Service in order to signup.”

So I can not make the next step,

I do not know whether this is a Bug

You can through the website for the actual operation again, you will understand what I said

How can I solve this problem?

thank you very much

Ann
