Yeah I see nothing that using a local version that would cause that… Hmm next I would try mixing CDN ref and local ref for js/CSS try to pinpoint what one is making it buggy.

Looks like

../images/loading.gif

…/ means previous directory so off CSS is public/css you want public/images.

Ah I didn’t think of the image references! Yeah probably better off downloading the whole library when it requires the other assets too. Its likely soft linking at point of the css file and you’d need assets paths stored in reference to the CSS file.

How would things break from including it yourself? Just download the file from the links in your post and include them on your webserver it shouldn’t require any code changes beyond that. You also never know if they would take down an old version or if some outage will occur so I’d personally rather host them instead of relying on additional servers to work.
