title: PHP $_FILES is empty on a form that was working in the past
body: <p>I am not sure what the issue is but a client of mine is complaining that an image upload form is not working anymore (has been working for about 6 months). I have searched through endless similar topics here and have gotten no where. Please take a look and let me know if you can spot the issue. Thanks!</p>
