I own a site that has multiple blogs on one domain. Each blog is a separate wordpress install. The root URL is one wordpress install and is considered the main homepage as it displays an RSS feed from each blog so that blog posts from all the blogs will show up on the main homepage.
Each blog is then in a subdirectory and is a separate wordpress install.
My plan is too install this plugin on the main homepage wordpress install as well as each blog wordpress install. Will that cause any problems?
