We are using Contribute CS3 ver 4.1. For the last 3 weeks, I cannot publish a page if I try to upload a file with it. After it uploads the file and it's about to publish the page I get the following error "Server not accepting connections". I click cancel and then get "unknown error in contribute file state manager". I have spoken with my webhost and they do not see a problem on their side. On their log file, they say connection terminated. I have used a FTP client and my file is there on their webserver. After I get this message and discard my draft and open up the webpage again and edit the page, I create the link and point it to the file on their webserver and then I can publish the page with no problems. I have disabled Antivirus and firewall. I have tried my computer at home and getting the same thing. I don't know what to try next.
Can you try removing your website connection and creating it once again or editing your website connection?
