Form displaying blank page after submission

This is the form

It should display thank you page and also send email. But right now, on submission it shows a blank page - why?

Apologies, we had a brief issue with EU based forms that should now be fixed.  If you have any further trouble with your forms not submitting, let us know and we will be happy to have another look.
