    Only Tom Cruise can divide by zero! 😊

    I haven’t played with DOMPDF in a minute, but what I do recall, it didn’t like something with certain styling information. Try pulling out all of your embedded stuff and your css, format with just regular html tags (
    , ) and see if it spits out anything. Also I think you need to do a string count or something with stream (or I might be thinking of something else) and pass it along as I think it added the Content-length: header.
