I've already installed the Simple Sitemap plugin from here (https://premium.wpmudev.org/project/sitemaps-and-seo-wordpress-mu-style) and made the requested change to the htaccess file. This (in theory) will create a separate sitemap.xml for each of my sub-domains site on my multisite. But I also want to install WPMU DEV SEO, for it's other SEO features. Can someone tell me what to do here? If I go ahead and install WPMU DEV SEO, will it cause conflicts with the Simple Sitemap plugin?
