I am unable to view the form because it requires a login. You can post login info here as a private reply so I can take a look.
Here are the errors:
- Failed to load resource: the server responded with a status of 500 (Internal Server Error)
- Failed to load resource: the server responded with a status of 504 (Timeout while reading response from Server)
It seems the server is blocking access to a core WordPress file.
My suggestion is to first resolve these two errors to see if the bio box issue is resolved too.
Hope that helps, let me know.
