    Why does "You have uploaded an invalid image file type" appear when I upload ANY type of file?

    Asked by utcompliance on April 04, 2014 at 10:08 AM

    Specficially, this is showing on the official visit checklist form. When trying to upload jpg, word, excel, or any other file, this message appears.

    I tried to upload a screen shot to the bottom of this page and I am getting the exact same message!!
