Galleria Reload code

I’m looking for a reload code for Galleria gallery plugin
https://galleria.io

I’ve tried
jQuery.get(‘/js/gallery.js’, function(data) { eval(data); })
jQuery.get(‘/js/galleria.classic.min.js?v=1’, function(data) { eval(data); })

Both scripts load but I get an error in the corner of my screen (an galleria error): No theme CSS Loaded

Could you please provide me of a reload code?

Many thanks in advance.

Eric
