I am using the Google Analytics for WordPress plugin.
I have set it to display the code in the footer, and this seems to be working fine. But there is an additional snippet of code added to the header:
<script type="text/javascript">
window.google_analytics_uacct = "UA-xxxxxxx-x";
</script>
(The x's represent my google account).
I was curious about what this item in the <head> section was. I deactivated the plugin and it went away, along with the full tracking code in the footer.
Thanks!
