The "Registration is not active" is shown when there are no active categories that people can register for, or if the current date and time are outside of the registration period for the program.
If there's a "Registration is not active" message on your registration form, please check the following:
- in Settings > General make sure the period set within Applications period starts/ends includes the current date and time. By default this is also the period in which people can register for the program. If you've selected the Set different registration period option, make sure the Registration starts/ends period is set to include the current date and time.
- in Settings > Categories see if the categories are set to Hidden status. For the program registration to be active you need at least one application category that is set to Public status.
