I notice that your image titles have the word "advert" in them.
It looks like you might have Ad Blocker extensions installed in your Safari and Chrome browsers which are preventing your gallery from displaying.
Try temporarily disabling any Ad Blocker extensions that you might have installed to see if this helps.
Such extensions are written specifically to search web pages for terms such as "ad" or "advert" and then block matching content, filtering the web page and essentially interfering with the intended display of the web page (albeit with good intentions).
As there is no way for a web page (or Juicebox gallery) to disable an Ad Blocker extension or circumvent its behavior, the best course of action would be to remove all text from your gallery which could be seen to be relating to advertising of any kind.
This should hopefully resolve your problem.
