What type of file are you trying to upload? Kongregate supports Flash (.swf) and Director (.dcr) files, but we don’t support .exes, or java games at the moment. This error usually happens when the developer tries to upload a game format that the site doesn’t support, so that may be what is causing it.
well it wont let me make any games i got to upload and that was as far as i could go then i tried making 4 more other games and the WOULDENT GO THRU.mabey the website dosen’t like me **well tell me whats goin on wit the website plz THANK U ALL FOR THE RESPONSE I MIGHT NOT GET**
If you want assistance, it helps to be specific.
Saying “it doesn’t work” doesn’t tell us anything about what problem you’re having.
What are you trying to upload? Does it consist of multiple files? What’s the filesize? filetype? Does the file have correct headers?
