I just installed NextGen Gallery so that I could activate the Pro version.
When I try to go to the options or settings page, I get the following error:
<strong>RuntimeException thrown</strong> /wp-content/plugins/nextgen-gallery/products/photocrati_nextgen/modules/nextgen_basic_album/nextgen_basic_album_gallery_display_type.php is not a valid MVC template
FWIW, this is activated on a single site of a network install. I would like to not network activate the plugin.
