How to disable lightbox on Woocommerce 2.3?

Thanks, but this is the problem: I haven’t that option in that page!!! My woocommerce is the 2.3.3 version.

That screenshot was from 2.3. Maybe something such as a theme is hiding it?

I’ll investigate it. I’m using a theme called Enfold that is updated and compatible with latest woocommerce. I’ll ask also to my theme support

Same problem here.
I’m using WooCommerce 2.3.5 and the lightbox option is unchecked but still opening.

Is that something I can do in my functions.php file?

I think the problem is the theme. (mine is Enfold)
The solution is to disable the lightbox of woocommerce in functions.php theme file. So add this:

//DISABLE WOOCOMMERCE PRETTY PHOTO SCRIPTS
add_action( 'wp_print_scripts', 'my_deregister_javascript', 100 );

function my_deregister_javascript() {
	wp_deregister_script( 'prettyPhoto' );
	wp_deregister_script( 'prettyPhoto-init' );
}

//DISABLE WOOCOMMERCE PRETTY PHOTO STYLE
add_action( 'wp_print_styles', 'my_deregister_styles', 100 );

function my_deregister_styles() {
	wp_deregister_style( 'woocommerce_prettyPhoto_css' );
}
