This is a condensed and improved version of an issue I documented here:
WordPress version: 3.5.1
WordPress SEO version: 220.127.116.11
I did this: I input %%POSTLINK%% into Facebook php sharer (or others) like so: http://www.facebook.com/sharer/sharer.php?u=%%POSTLINK%%
This method works in the old plugin RSS footer (also by Yoast)
I expected the plugin to do this: Output a correct sharing link in my RSS like so: http://www.facebook.com/sharer.php?u=http://mysite.net/title-of-post/
Instead it did this: it wraps a <a href=""></a> around the post permalink therefor breaking the Facebook php sharer (which only needs the link, without the added tag) like so: http://www.facebook.com/sharer.php?u=<a href="http://mysite.net/title-of-post/">Title of Post</a>
What I would like is to get rid of the link tags: the permalink of the post itself is enough: I can add the HTML myself.
