If you’ve submitted any type of form recently, you may have noticed that you end up with a blank page with “ï»¿” as the only source of text. It may seem that the form was never sent, but if you filled everything out correctly, it’s been mailed and received. For some reason, the redirects (redirecting to confirmation/error page) are not working, though the forms still get mailed out.
The problem is being looked into. In the meantime, you simply will not know if a form has been successfully sent out. Just make sure that you properly fill out any required fields.
