https://www.gaytor.rent/doupload.php works fine for me, but, like you, I find QTM presents code instead of categories. I reported the issue a while back (around 7th April) and got this response: "The site admin is working on updates and fixes to QTM as we speak.
Please wait a week and try again. In the meantime, uploads need to follow the manual instructions."
It's over a week now, but my guess is that we just have to be patient as they are aware of the problem and are working on it.
Hope that helps.
