As you suggested some time ago, we follow all your indications and:
1. We bought the premium version
2. We clicked the refresh webinar form button in settings
3. WordPress is latest version and all plugin are updated.
4. These are the questions of the original form, not shown in the form: https://attendee.gotowebinar.com/register/3517311674092932353
It is very urgent for us solving this issue.
thank you so much
