Hi,
I noticed that if functions.js is called in sub directories, it fires 404 error for preloader.gif and blank.svg in some cases.
I found that the source urls are not formed relative to the root. You may consider to correct it in future releases.
Current code:
element.attr( 'src', 'images/blank.svg' ).css({ 'background': 'url(images/preloader.gif) no-repeat center center #FFF' });
Should be:
element.attr( 'src', '**/images/blank.svg' ).css({ 'background': 'url(/**images/preloader.gif) no-repeat center center #FFF' });
