Issue: Publicize fails to post to Facebook
Imagine you got a valid connection to a Facebook profile or a page. Well, imagine that after publishing a new post, nothing happens in Facebook. This does happen and it turns out it’s a pretty common issue among users with an attraction to social media propaganda.
The problem usually is related to a conflict with another plugin that ads Open Graph meta tags in the header. WordPress SEO, Social Graph Protocol and many others do it and when they are activated together with Jetpack Publicize you’ll get the problem.
Fixing is easy, if the other plugin is not that important or if it has a feature for disabling OG tags. You just deactivate it. Otherwise you’ll have to make up something smart that will control the Open Graph output, either from Jetpack Publicize or from the other source.
