Using a corportte server (don't know where it is or who the administrators are) we used the "create a site" on the portal. The server was http at the time of the site creation. Sometime later it was converted to https. Now, some of the preloaded themes cause a popup box to appear everytime you click on a new page. The box says: "This page contains both secure and nonsecure items. Do you want to display the nonsecure items?" With some of the themes this does not happen. I used out of the box tools, don't have access to the server, have administrative rights, nor know who does. Does anyone know how to tell what within these themes is causing this mixed content warning and how to fix it? Thanks. My browser security is checked to allow mixed content but I still get the box and so does everyone else.

This question is unlikely to help any future visitors; it is only relevant to a small geographic area, a specific moment in time, or an extraordinarily narrow situation that is not generally applicable to the worldwide audience of the internet. For help making this question more broadly applicable, see the FAQ.
You can use tools like the Internet Explorer Developer Tools (hit F12 with IE open) or Firebug in Firefox to track these down or just do a view source of the page and look for http://. The likely culprit is a link to a stylesheet or external script like a CDN copy of jQuery or something that is not being delivered over https, and thus throwing the mixed content message.
