Take note of this


Hmm, I don’t know exactly what could be causing this. “400 Bad Request” simply means that the server doesn’t like your input. But what’s wrong with your input, or what is refusing the request to begin with, I don’t know.

Could you please answer these questions to help figure it out?

  • How big is the file you’re trying to upload, and what is the file type?
  • What does the error page look like exactly? A screenshot of the page could help us determine what generated it.
  • If possible, could you provide a link to your page so we can try it ourselves?
