I am unable to input into the name and email on my website even though ok on preview here?

The Url is just one of my forms, but it appears to have happened on them all, some to more of an extent, i have messed around creating a new form just to find it did the same?

This is a duplicate thread. I already posted my reply on the other thread. Here's the URL: https://www.jotform.com/answers/835045

Thank you.
