It took me some time, but I'm sure this may have come up before. I was attempting to purchase products from Adorama.com and when it came down to filling out the credit card info at check, One password filled out every fill correctly, but the site would not accept it. I manually copied and pasted all fields from one password extension into the correct location in the form. It accepted it without issues. I been running into this issue often with others sites.
