When I use Windows7 everything works pretty well.But yesterday I installed elementary os and today when I tried to submit my solution some problems occered.I always get "No data received" with "Error code: ERR_EMPTY_RESPONSE" after a click the submit button.My browser is Chrome. Meanwhile I find that if my code is short enough(in about 50 lines),some times it be submited successively. I googled for the afternoon but find no result.Can anyone tell me how to solve it?Thanks a lot.
