I purchased and installed a Comodo cert.  I've put the logo code in my header and footer files, and everything works fine.  The problem occurs when you move to checkout and the browser goes into secure mode.  Comodo provides two certification sites; one secure and the other un-secure.  How do I accommodate both when using a common header & footer.asp file?  There's probably an obvious solution since Comodo is recommended by PC, but it's escaping me.

Thanks in advance for any help.

I also had some problems, and one was caused by their new look with the scroll up and down logo.  The other by not loading the image securly.   Simply add the "s" to the "http" with the image in your header and it will stop it.  I also reverted bag to their older version without the up and down scroll.  Took me a while to find it on their site.  It was kind of hidden.  To see how it looks on my site go to http://www.germanplaza.com - www.germanplaza.com   Here is what you have to do:

In the header you have to add:

<script language="JavaScript" src=" https://secure.comodo.net/trustlogo/javascript/trustlogo.js - https://secure.comodo.net/trustlogo/javascript/trustlogo.js " type="text/javascript">
</script>

In the body:

<script type="text/javascript">TrustLogo(" https://www.xxx.com/secure_site.gif - https://www.xxx.com/secure_site.gif ", "SC");</script>

Remember to exchange the http://www.xxx.com - www.xxx.com for your url.  The logo you will find on the comodo website.

Thanks - that did the trick - I was right, the solution was deceptively simple -  thanks. By the way, both sites look good - I came away with a couple other ideas after reviewing yours.

Thanks,

Whenever you have a ssl page you need to make sure all  images and scripts are either referencing the content with a local paths or are using https:// to access the content. Otherwise you will get a error thrown by the browser due to insecure content trying to be loaded.
