Be sure to check your settings in the Presenter Portal under both Settings and Content. For example, if a field under “Additional Information” is checked as mandatory in the Content section, you must also include the “Additional Information” section when creating the Settings for the portal. If you don’t, the presenter will get an error message when they try to submit.
Another possible cause is that they’re trying to submit for a second (or third, etc) time. There is a setting designed to prevent too many submissions from the one author: Maximum number of papers an individual can submit. When it’s set to 1, each author can only submit one Abstract via the Presentation Portal. However, it’s easy to increase the limit if you need to. Before changing this setting, please check any relevant business rules within your organization.
