Certificate errors
When using a certificate through either the Digitally Sign or Certify (Visible Signature) options, multiple errors occur that prevent the signature from being successfully applied, even after completing the signing process. In some instances, the signature appears to process and load but then disappears as if it was never applied. Other times, error messages are displayed saying that the document is open by another user (when it is not), the byte range is invalid, or there is an error displaying the signature. In some cases where an error says the signature cannot be displayed, closing and reopening the PDF may show the signature (sometimes). The issue is intermittent but frequent. It is often necessary to repeat the signing process multiple times before the signature is successfully applied. In some cases, it would take at least five attempts before it would complete successfully.
