Here are four reasons why you do not see the Submit abstract button in your abstract submission form:
1. Global last date for submission deadline has lapsed. Look under Submission Settings. See screenshot below.
2. The abstract submission is only enabled for authors who paid the abstract submission fee. Look under Submission & Review Settings. See screenshot below.
3. The selected submission type's date has lapsed. Look under Submission Types. See screenshot below.
4. The selected submission type is not allowed for the usertype currently logged-in. Look under Submission Types. See screenshot below.
