  • Getting this error, too. Happening with Treeson version 0.1.13 using WP 4.4.1. Not getting error with other themes. Tried disabling plug-ins and it’s not creating issue. I tried this fix in functions.php.

    1) move this line
    add_action( 'admin_init', array( 'mythemes_gallery', 'admin_init' ) );

    2) here to make it conditional. 

    if( get_theme_mod( 'mythemes-gallery-style' , true ) ){
		add_action( 'admin_init', 	array( 'mythemes_gallery', 	'admin_init' ) );
        add_filter( 'post_gallery', array( 'mythemes_gallery', 'shortcode' ), null, 2 );
    }
