I used the Thin Out Revisions on one site using this theme, and I’m able to use it fine, however on my second site, when I installed all the same plugins, including Thin Out Revisions, this time I can’t see it on any of the revised posts or pages. (I uninstalled and reinstalled this plugin and have even ticked the revisions button on the screen options but that doesn’t change anything. Please help soonest. Thanks.

I’m not convinced it’s a theme issue, since you say that it works fine on your other website. You can find out easily though, by switching to other theme to see if that solves the problem. Either way, I never worked with this plugin, so your best shot is to ask plugin author for help.
