Changing over to https

[Panzer Max]

So, finally started the fun of getting our site switched over to https. Forum is working, most of the rest of the site is getting the sacred padlock.

But the forum does have ONE image that is mysteriously showing up as not cooperating.

An image with an insecure url of "http://www.subsim.com/radioroom/images/icons/icon1.png" was loaded on line: 742 of https://www.subsim.com/radioroom/index.php.

Ok, so it sound like maybe that one icon was hardcoded into a template or php file somewhere, god only knows why. I have searched all the templates for icon1.png and http://www.subsim.com.... nothing!

I've checked the Styles CSS and MainVar section... nada!

I've dug through the php files. Cannot find it.

So, the friendly folks at vBulletin suggested using a 301 redirect and that will work, but now I want clean up as much as I can, and I gots to know, just where can I find where vBull sets the "thread icons" ?>?

Edit: Wayne+Omnibus pointed me in the right direction, vBulletin Options/Thread Display Options
