For reference, the specific Facebook Javascript code we're looking to remove is:
<!-- Facebook SDK -->
<div id='fb-root'></div>
<script type='text/javascript'>
// Load the SDK Asynchronously
(function(d){
var js, id = 'facebook-jssdk'; if (d.getElementById(id)) {return;}
js = d.createElement('script'); js.id = id; js.async = true;
js.src = '//connect.facebook.net/en_GB/all.js';
d.getElementsByTagName('head')[0].appendChild(js);
}(document));
</script>
<!-- End Facebook SDK -->
If you have sh404SEF installed, the plugin you'll want to disable is the "sh404SEFcore - Social buttons plugin" in the "sh404sefcore" plugin group. Hopefully, that's what you're looking for, though it sounds like you may have already found that.
Once disabled, make sure you clear your Joomla (or Jot) cache. If that doesn't work, can you Private Message us admin credentials for your site? We'll gladly investigate further.
As for iPhone, we'll have to do some more testing. That may be something we need to fix with some media selectors in the SCLogin module's stylesheets to properly detect the mobile environment. For now, I'd recommend editing the /media/sourcecoast/themes/sclogin/sourcecoast.css file. At the bottom, add the following:
.sourcecoast.modal.fade.in {
top: 5% !important;
}That will shove the box up higher. The default value is 25%.
I hope that helps, but if run into anything else, just let me know.
Thanks,
Alex
