jetpack gallery not working properly

Hi

I can’t seem to get the jetpack gallery (eg tile mosaic) and carousel to work properly. I’m using the stargazer theme. I’ve installed the cleaner gallery plugin – that didn’t work. I’ve tried adding :

function child_theme_setup() {
remove_shortcode(‘gallery’, ‘gallery_shortcode_tbs’);
add_shortcode(‘gallery’, ‘gallery_shortcode’);

}
add_action( ‘after_setup_theme’, ‘child_theme_setup’ );

to the function php as recommended in an earlier post.
I’ve tried adding
remove_theme_support( ‘cleaner-gallery’ );
as suggested in Theme Hybrid.

Nothing is working. I always get simple thumbnails and the message “Jetpack’s Carousel has been disabled, because another plugin or your theme is overriding the [gallery] shortcode.”

Can you suggest anything else ??
Thank you !!!
