I am posting this here as it’s not really a question unique to a particular plugin, but common to most lightbox plugins that support display of external URLs in a lightbox (e.g. JQuery Colorbox, Shadowbox, etc). My question is why do these plugins result in an error “Domains, protocols and ports must match” on some websites, but not on others. And why should a URL that loads perfectly well in a plugin like “Simple Popup” then throw this error when you add “rel=lightbox” to display it in a lightbox?
I get that this is a problem with the way Google Chrome applies browser security. But why only for lightboxes, and not for other kinds of popups? Is there anything that can be done about it? In my case, I have no control over the URLs I want to display in the lightbox – e.g. Google Maps, Agoda location maps, etc.
