Hi!
This should not come from the theme as far as I know, unless alx_embed_wmode_transparent {} affects it, which I don’t think it does.
No, it’s not that piece of code in functions, the code remains.
Checked it one more way: applyed twentythirteen theme: no oauth code, reinstalled hueman – this iframe appears like this:
<!--[if lt IE 9]>
<script src="mypath/js/ie/respond.js"></script>
<![endif]-->
<iframe name="oauth2relay77777" id="oauth2relay77777" src="https://accounts.google.com/o/oauth2/postmessageRelay?parent=http%3A%2F%2Fmywebsite.com#rpctoken=77777&forcesecure=1" style="width: 1px; height: 1px; position: absolute; top: -100px;"></iframe>
maybe it’s nothing wrong, but as i’m not a programmer i always feel worried if I see some unknown code or hidden iframes.
By the way, in your theme you have texts in comments form with display=none, “requed fields”, “tags you may use”, the thing is that google indexes this text and even shows up in some snippets.
Aware of the display none inline css – should be fixed in the next update.
I’m pretty sure that iframe code must come from some plugin, as the demo site does not have it.
It’s just a code added by Google+ button 🙂
