[SOLVED] Upgrade Excerpt Difference in More Action / lost pictures, blackbirdpie twee

I had to upgrade from 3.5.4 to the current version of the theme for security reasons. (I know, I know , I should have done it a while ago but we had made a number of changes and were happy with the site)

In 3.5.4 version I found that if I put in the more tag where I wanted to split the post, I got the added benefit of the picture showing up, blackbird pie showing tweets, vimeo windows showing, etc.
Now in 3.7.7 that's all gone.

Is there any way I can go back to selecting where I want the excerpt to end and maintaining all of the pictures, video, blackbird pie tweets (basically exactly the same look as the full post)?

Thanks,

Dale
