[Plugin: WP-Polls] error: fvd is not defined

Disable all plugins and try, does the poll works normally on the front page?

poll works normally I guess. This error is on admin page when I open Blog Stats link:

Permission denied to call method Location.toString
createAJAX()()tw-sack....ver=1.6.1 (line 43)
sack("https://ditfi.lv/wordpress/wp-content/plugins/wp-polls/polls-admin-ajax.php")tw-sack....ver=1.6.1 (line 192)

polls-admin-js-packed.js?ver=2.31()()polls-ad...?ver=2.31 (line 1)
[Break on this error] this.xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");

There are no errors when I deactivate WP-Polls plugin, and I don’t find errors after deactivating Wp-Stats. There could probably be a conflict between these plugins, but I’m not sure.

now error is on front page!
It showed up after I added some analytic script to page footer:

<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "https://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script src="https://www.gmetrix.lv/search.js" type="text/javascript"></script>
<script type="text/javascript">
var pageTracker = _gat._getTracker("UA-6213582-1");
pageTracker._trackPageview();
</script>

I am using WordPress Stats myself and it works fine for me. One of your JS script must be malfunctioning and hence causing any JS not to work after that.

I am getting a similar error that has to do with tw-sack.js – please see

I have listed the problems there as well as in this Google Group:
https://groups.google.com/group/firebug/browse_thread/thread/e7efb8421bf8dcb8

First, I thought it was a Firebug problem, but it seems to be originating from the way the AJAX request is made in tw-sack.js.

I have converted the plugin to use jQuery in the next update
