Guests cannot create posts using forms that include File or Image fields when Access is active

Symptoms

There is an issue where users that are not logged in cannot create posts using Toolset forms. It happens in the following case:

• The Toolset form includes at least one file or image field.
• The form is using AJAX for submission.
• Access is active and configured to allow guests to create posts using the form.

When you submit the form, you get the success message but the post is not created.

Workaround

Until we fix this issue, as a workaround, you can disable AJAX form submission in the form settings.
