Fix for duplicated images in lightbox

To fix this, please replace whole “if” statement that starts on line 95 file “inlucdes\js\gallery.js” with:

if( jQuery().magnificPopup) {
			$('.gallery-link-file').each( function() {
				var $this = $(this);

				var delegate = '.gallery-icon a';

				if($this.hasClass('wcflexslider'))
					delegate = '.gallery-item:not(.clone) .gallery-icon a';
				else if($this.hasClass('wcowlcarousel'))
					delegate = '.owl-item:not(.cloned) .gallery-icon a';

				if ( $this.hasClass( 'magnificpopup-is-active' ) ) {
					return;
				}

				$this.magnificPopup({
					delegate: delegate,
					gallery: {
						enabled: true
					},
					type:'image',
					image: {
						titleSrc: function(item) {
							var caption = $(item.el).parent().next('.gallery-caption').html();
							if ( 'string' == typeof caption && caption.length > 0 )
								return caption;

							return '';
						}
					}
				});

				$this.addClass( 'magnificpopup-is-active' );
			});
		}
