I have used both pagelines pro and pagelines lite for a little while now. One thing I just discovered is that pagelines lite does not place the Open Graph Protocol tags in the head tags, it places it in the body which completely messes up everything when you try to share posts or pages on facebook. I checked out my links in the facebook debugger to confirm that this is the case.
Also, if i try to use a WordPress Open Graph plugin to fix the issue it seems to just conflict with pagelines regardless of checking or unchecking the "display Facebook open graph tags in the header".
Any thoughts or suggestions?
