Ye' old general discussion board. Basically, for everything that isn't covered elsewhere. Come here to shoot the breeze, shoot your mouth off, or whatever suits your fancy. This forum is not for asking programming related questions.
I'm using cURL to POST a bit to their site, just sometimes it works fine, sometimes I get the nice yellow error you have just experienced. weird stuff just wanted to check if my vars are all ok.
Their web app seems to be pretty unstable. It's working now.
To check all POST vars sent by that page, save the HTML on your machine and make all forms point to a script of your choice. Submit, and print_r($_POST) in the destination script. Voila!
