Hello, I am assuming the technical support a company that has been using Salesforce (professional) and Constant Contact together for a while. Recently, for no discernable reason, the sync between the two ceased working. I installed the latest version and then added the button to the Contacts tab in Salesforce. When I use the button to upload a Salesforce contact to Constant Contact, an error is displayed "Upload Failed" and the associated comment is "Internal Server Error". The funny part is that the contact actually gets synced to Constant Contact. Please see the attached image for more info. Can you tell me what I need to do to either eliminate the error message and or help the system see that the sync actually worked? Thanks, Eric
