How i Solve this error?

Answer 1

I believe your problem is that your blueimp gallery is initially hidden as it is in a Bootstrap Modal. As such, when you first initialize the gallery it can't find the gallery. I think all you need to do is wait for the Bootstrap modal to be shown and then initialize the gallery.
Bootstrap triggers an event that you can listen for for this very purpose - http://getbootstrap.com/javascript/#modals-events - You probably want the shown.bs.modal event.
You would use it something like this. (assuming jQuery is loaded)
$('#portfolioModal1').on('shown.bs.modal', function (e) {
blueimp.Gallery(
document.getElementById('links').getElementsByTagName('a'),
{
container: '#blueimp-gallery-carousel',
carousel: true,
}
);
})
Bear in mind this is untested code and may not 'just work'. But hopefully you get the idea. You also may want to do a test to see if you've already initialized the gallery, as it stands this would re-initialize it every time the shown.bs.modal event was fired.
