I initially added the Open Graph plugin to fix sharing on Facebook, because Facebook was ignoring the Featured Images chosen in WordPress (no og:image tag in the header). It worked great for that.
I am having a problem with sharing on Google+ though.
I have Yoast's WordPress SEO plugin installed which already places some Open Graph tags to the header. WP Facebook Open Graph adds those yet again.
So, whenever I try to share a link from my website on Google+ is shows the title and description twice. Facebook ignores the duplicates, but Google+ adds them inline.
Is there any way to prevent this plugin from placing duplicate og:title and og:description tags in the title?
