I found a MUCH easier way to make this work, without all the modding. All I had to do was change "http://" to "https://" in the original code near the bottom of ..skin1/customer/home.tpl. I only changed it in that one spot from the code I was given by Comodo.
PHP Code:
<a href="https://www.instantssl.com" id="comodoTL">SSL</a>
<script language="JavaScript" type="text/javascript">
COT("https://www.mysite.com/skin1/images/secure_site.gif", "SC2", "none");
</script>
Is there something else that the mod in this thread does that my change doesn't do?
