[Plugin: WordPress SEO by Yoast] Cannot remove OpenGraph meta data Tags

I thought this should be an easy question for Yoast/Wordpress users, and popular one…

Anyways here is my website, if it helps, I’m still craving for an answer:

(yes, it’s in Hebrew)

Looking at your website, it seems like you managed to remove the og meta tags. If so, could you share how?

Go to file name: class-opengraph.php

At the bottom of the page, remove/comment-out the following two lines:

global $wpseo_og;
$wpseo_og = new WPSEO_OpenGraph;

This is it. ??

finally. Thanks!!
