 * I am using version 3.7.1 of your plug and get error that says Upload Failed! 
   Unknown Error. I upgraded to see if I can get rid of this problem with file uploads.
 * To create this error upload PDF file (which might work or might not work), close
   Chrome browser and try to upload the any PDF file and this error will show.

 * Any advise would be much appreciated.
 * Thank you in advance.
 * P.S. Thank you for all your hard work on this plugin.

 * Hi Nickolas,
 * Here is the shortcode.

 * I tried so many shortcut variations. Seems to function with no issues once I 
   am logged in as admin.

 * I tried now as a visitor and it worked, do you still face the problem and if 
   yes in which browser?

 * Hi Nickolas,
 * Yes I still have the problem.
 * I am using Chrome browser. Like I said above it works sometimes and it doesn’t
   work sometimes.
 * I have attached screen shot of the error. If upload works.. just totally close
   the browser.. revisit the page and try to upload again and it will not work.
