Q: What does the "SIG" error mean on the File Exchange Sync Chrome Extension?
A: It's a Sign In Error. This means that eBay signed you out of eBay file exchange at some point. Please go directly to eBay File Exchange ->> https://bulksell.ebay.com/ws/eBayISAPI.dll?FileExchangeUploadResults&ssPageName=STRK:ME:LNLK and if eBay is asking you to sign in, please do. If you are already signed in, then you can go to the Logs tab of your extension and clear Clear All Logs to get rid of the alert.
