PowerForm error: This document may no longer be signed

Error

Unable to submit form data. Error: This document may no longer be signed. Please contact whoever provided you with this document for further details.

Cause(s)

Issue 1:
The PowerForm administrator has set a limit for that particular document and the limit has been reached. As the error states, you will need to contact the PowerForm's administrator to clear or reset that limit.

Issue 2:
The PowerForm Sender user account was closed so the PowerForm no longer has a Sender associated with it.

Solution(s)

Solution 1:
This error is related to a limit set on an individual PowerForm. It is not related to any account-wide document send limits.
If you are the PowerForm's administrator, you can reset that limit by following these steps.

Steps:

From the home page, select Templates
Click on the template with the active PowerForm to open the Details page
In the Associated PowerForms section, select Actions > Edit PowerForm
In the Edit PowerForm panel, you can either uncheck Set Usage Limit by Quantity to remove this restriction, or change the Maximum # of Submissions appropriately.
Click Update - the change will take effect immediately and the PowerForm will be available at the same address.

Solution 2:

If you are the PowerForm's administrator, check to see if the PowerForm has a sender associated with it (Manage > PowerForms)

If the PowerForm Sender user account was closed, you will need to change the PowerForm Sender to someone else that is active on the account.
