i have added the code into the plugin field, but the service website say that the code is not installed, th same happen if I put the code by hand on the head or on feet, maybe something is wrong on plugin ? or maybe theme have some conflict?
<script type="text/javascript">document.write(unescape("%3Cscript src='" + (("https:" == document.location.protocol) ? "https" : "http") + "://e.mouseflow.com/projects/e8986e13-aed0-4555-a312-3706a5ee501e.js' type='text/javascript'%3E%3C/script%3E"));</script>
