Hi:
I was having the same issue & found the solution:
Jquery is adding width:auto; to the body tag.
You just need to comment out the lines 15 – 17 in: wp-content/plugins/file-away/lib/js/management.js –
they look like this:
// FLASH BODY WIDTH FOR WEB FONTS
15 setTimeout(function(){
16: $('body').width($('body').width()+1).width('auto');
17 }, 500);
Hope this helps anyone who is having the same issue.
