Why your form says registration closed
If your form ever shows the below message, and you are not sure why... Panic! Just kidding. It is a quick and easy fix.
It is likely because the Limited Supply option was set on the Basics tab of your campaign and the set limit was reached. In the example below, the Limited Supply option was selected, but a number was not entered into the box to indicate the desired supply. Since it says '0 of 0', the form will close since it believes the supply limit was met. To reopen your form, simply select Unlimited, or increase the available supply.
If your form ever shows the below message and you are not sure why....
It is likely because the Registration Opens date is set for sometime in the future. Or the Registration Closes date is set for sometime in the past. To reopen your form, either delete out both dates. Or simply make sure the open date is sometime in the past and the closes date is sometime in the future.
