Corporate Theme-HTML Editor Not Working

I may be barking up the wrong tree here, but I wanted to see if this has happened before and if there is any solution that has come out of it.

The HTML tab for adding/editing posts or pages is not working on my Corporate Theme Buddypress site. I switched to a different theme and it works, so I know it has something to do with the theme files. I also have deactivated all plugins to try and isolate one of them that may have been causing the problem and still no luck. So at this point I'm just trying to do all of the outreach that I can to see if there is some solution that I'm overlooking.

Any help would be greatly appreciated!
