javascript未在ssl上加载

I've a WHMCS installed on my host. I've just added a simple code to rotate our certificates logo and it's working fine in the main page (and also Non-SSL pages), take a loot please (down in right column of the page):

http://www.irpowerweb.com/

but in SSL pages it's not working:

https://www.irpowerweb.com/register.php

eth is same in both paths and the only difference is about SSL (HTTPS).

I find out the problem is not related to the insecure content on my page ('enamad.ir/trustseal/symbol.aspx') because I removed it but problem exists.

any helps are appreciated.
