I'm getting an error trying to use the pro features with NextGen Pro. I'm trying to use the PRO version of a thumbnail gallery and get this message:
Fatal error: Call to undefined method Mixin::initialize() in /home/roddason/public_html/wp-content/plugins/nextgen-gallery-pro/modules/nextgen_pro_thumbnail_grid/adapter.nextgen_pro_thumbnail_grid_controller.php on line 7
Has anyone seen this before? Any fixes? The basic thumbnail gallery works, just not any of the pro features. It installed without issue. If I change to FILM STRIP PRO the referenced error changes to:
Fatal error: Call to undefined method Mixin::initialize() in /home/roddason/public_html/wp-content/plugins/nextgen-gallery-pro/modules/nextgen_pro_film/adapter.nextgen_pro_film_controller.php on line 7
ALWAYS LINE 7. Any help is greatly appreciated.
