Here is the latest update from Intuit:
Latest update: This issue was caused because a Symantec Root certificate, used in the development of applications, was revoked. This resulted in many certificates to be considered invalid. To maintain the highest security, QuickBooks is designed to only allow applications with valid certificates access to company file data. This may appear to be a QuickBooks bug because that is where the warning appears, but Intuit is actually detecting invalid certificates and is blocking access to company file data as it should. Intuit is just one of many developers that have been impacted by this recent event. This issue will be completely resolved once any developer using expired/invalid certificates update their apps accordingly with a new valid certificate.
Intuit continues to take the necessary steps to update our certificates, and other 3rd parties will need to do the same. First step was to release patches for our supported versions of QuickBooks. These patches deliver the newly updated Web Connector which has been mentioned in the help article we recently published found at intuit.me/cert. These patches only update the Web Connector app, so if a customer is using a 3rd party app that doesnt use Web Connector to sync data with QuickBooks this update will NOT resolve that.
Sounds like Intuit is blaming third parties. Third parties blame Intuit. This is getting crazy.
