I keep getting "There was an error on the page. Try reloading the page".

I cannot save or preview my form as I get There was an error on the page. Try reloading the page.

Sorry about this, there was a temporary glitch with our European DNS system. Our developers informed us that this is already resolved, can you please try saving and previewing your form again, and let us know should you be experiencing any further problems.

Thank you.
