Hi!
I found the problem. The jQuery script is missing from the header, so the plugin cannot initialize.
I see two other errors related to this as well in the console. One is a revolution slider ajax content loading script, and the other is some kind of fluid video wrapper. They both report the same error as related posts lite.
I suggest moving the jQuery back to the header from the footer, because many javascript related plugin depend on it, and if it’s not properly loaded, errors will keep appearing in the console.
