Why is my form "Not Found"?

I've created multiple forms and they work at first and then once I put them on my site, they become disabled. Please advise.

Hello,

I have checked your account and your form named "Club Casa Online Booking Registration". I have seen that your account has been auto-suspended by our automatic phishing detection system due to phishing.

Please note that you are not allowed to receive any password information from your users. This is the reason you have been detected by our automatic phishing detection system.

I have deleted the forbidden fields according to our terms of use and then I have reactivated your account.

Please avoid this kind of activities in your account.

Thank you.
