Fatal error: Cannot redeclare class Nav_Menu_Roles_Import in /path/to/wordpress/wp-content/plugins/nav-menu-roles/inc/class.Nav_Menu_Roles_Import.php on line 12
I'm running WP Multisite here. Installed the plugin on my network and activated across all sites. Went to Tools > Import on a network sub-site and got the fatal error above. Can't even select which import method to use, never mind import any XML file.
