We have installed the digital signature plug-in for our user's Web Access since her signature gets appended by workflow when routed for approval but Web Access was throwing the certificate error message when clicked. https://answers.laserfiche.com/questions/155935/Certificate-not-found-9418-on-Web-Access#155941. The certificate error has been resolved since installation.
However, her certificate continues to fail to validate on Web Access (it validates on the client). Her name is displayed as the Signed by, which used to say Unknown before installation so that is good. However, when we click on the Show Details, it displays an error message; "Object reference not set to an instance of an object" .
We also confirmed that her certificate had been added to Metdata>Certificate Store share the same fingerprint as the one used by workflow.
Any idea as to why this is happening?
