Heateor,
I am very appreciative of this free plugin, but couple of issue are kind of defeating the purpose you set of the plugin. I am sorry to say these things to you.
1. After login (I use FB), the user basically loses his/her place since it takes them to the top. I tried several things including adding #commentform div in comment area thinking that it might be looking for that anker tag. I deactivated all my plugins, but no luck.
2. Post social login, it still does not show the comment box and it still says login to comment(this is approximation, not exact wording). Only the hard refresh can bring it. User will not know to do that and it is too much to ask. I tried everyone’s suggestion of putting ExpiresByType text/html “access plus 0 seconds” in my .htaccess file. No luck. Even if this were to work, it would sacrifice the site’s performance. These two issues leaves my in a dilemma of whether I should abandon the plugin I love.
