The unknown error occurs whenever it tried to buy an item, and the normal success or error messages do not occur. Possibly because of something messing with the html before the program gets it, or an abnormal theme on the site.
Oh, I see. I had my theme on Neopets Blue a couple of hours ago when I got the Unknown Errors so I changed it back to Neopets Basic before I posted that log above and it still had the same "Unknown Error". Any suggestions on what I should do?
