If you have enabled SSL it may happen that some browsers may block the resources that are not using the https:// in their url.

  While Chrome and firefox manage to work fine in some cases. But IE does give a strange behaviour.

I would suggest you to please cross check if any external scripts or images or styles that you are using in you website uses the http:// in their urls. If any please change them to use https://

It may not be the exact cause of your problem but since i faced this problem in one of my sites, I am suggesting this option.
