I cannot seem to leave feedback on a user here on SSO. He has created his account only a few days ago just to purchase an item I was selling. As a result, he has very few posts and is new. He was able to leave feedback for me but I cannot seem to leave feedback for him. It says "1. There was an error in your deal details!" even though I filled out every field. Is there a way I can fix this? I'm using google chrome.
