I'm running xenforo 1.1 with akiron theme 1.1. I have set the correct opengraph logo path in style properties. I verified the fact that forum_list template does include the og meta data. But when I view the page source for my forum home page, there is not even one og tag? Facebook's URL Linter is also unable to get the og meta data and shows four warnings. What could possibly be going wrong?
