Your form asks you to log in to your 123 Form Builder account if its activity is set to Active only for me.
With the Active only for me option, only you or your sub-users can view the form. Therefore, your website visitors will receive the following message.
To check your forms’ activity, go to My Forms and click on the three dots icon. Select Activate/Deactivate to open the status dialog box.
There you can choose the option that best suits your needs. If you want everyone to be able to access your form at all times, select the option Always active.
