Possible conflict with stockholm theme

I am using a theme called Stockholm, and we have noticed an error in our logs "We’re sorry, but your theme’s page template didn’t make a call to wp_footer(), which is required by NextGEN Gallery. Please add this call to your page templates."
I checked with the theme author who said: that NextGen is not officially supported by our theme and it may have some conflicts with it. Our page templates are using get_footer() function to include footer template which is using wp_footer() function.

Just wondering if you might have any advice as we need both the plugin and the theme if possible. We are using NextGEN Download Gallery plugin also to create downloadable media kits.

Thanks for your help,
Belinda

PS the media kit pages are actually password protected but happy to get you the password to take a look
