title: laravel.log is populated with errors, error screen is blank
body: <p>I'm developing on Laravel 5.4.  laravel.log is working perfectly fine, but when I experience an error, the user screen is white. When the screen is white if I view source, I see a bunch of html....</p>
  
  <p>Also, when I add dd() to my code, the screen is also white, but if I do view source I can see what is supposed to appear.   </p>
  
  <p>Would like to see the errors normally on screen.  It did work at some point, and I haven't done any upgrades to Laravel or MySQL, etc. </p>
