Stopped Working

I had this site in a subdirectory on my website during development and the tabs worked fine. But after transferring the site to a different server, they no longer work. The strange thing is that they no longer work on the test site either. Any ideas? I’ve tried deactivating/reactivating as well as reinstalling. I also tried downgrading to the last version of WP to see if that was it.
