All of the variables print out properly and it prints "sent MrLonely1221's data to website" but before that it prints the error "Content failed because HTTP 404 (HTTP/1.1 404 Not Found)". I do web development and know for a fact that my website is up and running. Does anyone know why I am getting this error?
