Goose, thank you so much. If possible, could you take aone step to confirm which one of those files is the right one (it might be both, in fact). Here's how to test it:
1) Reactivate Jetpack's OG tags by deactivating the plugin you installed (the https://github.com/sgthemes/Remove-Jetpack-Open-Graph-Tags/blob/master/RemoveOGT/index.php )
2) View your site's source and confirm that Jetpack's OG tags are there, along with Yoast's
3) If they are indeed there, then edit the class.jetpack.php file in your site, at about this line:
add one of the 2 file names, following the model there exactly, so as to not mess up your site. So, for example, at the end of the list, write it as such:
With the quote marks and the comma, very important.
Once you've edited the file, refresh your site and view source again, to see if Jetpack's tags are there. If they aren't, great, that fixed it! If they aren't, then try with the other file-name, /wp-seo-premium.php.
Let me know how that goes! If you'd rather not, then I guess we'll add both filenames so as to make sure it works.
