I was alerted by a user of my site that he could not read the rest of the content after he had liked and g+1'd the content via a comment on the post he was trying to read. So I went and created a test account, and lo and behold, he's right! No even Twitter is working, cause I tried that one as well. The only one I haven't tried so far is LinkedIn's button.
I wonder if this could affect my blog as well, since I also have this plugin installed there as well.
Looking forward to getting this issue resolved,
