Titles missing in IE 9

Hello, I’m the owner of the school ‘Pymspen’ referred to above. I’m still having this problem specifically in IE9 where ALL headers will first appear and then vanish once the page has finished loading. For example, if you go to the page http://www.georgetownatelier.com/events/ you will see the headers in red on the top appear and then dissappear. I’ve checked on a few other computers using ie9 and it’s the same problem so I know it’s not local to mine. We have an important event coming up (as well as info on other pages) and having these headers gone renders the pages useless and confusing.
I have the latest version of WP installed also.

ANY HELP IS VERY MUCH APPRECIATED. Thank you!

Thanks for the quick response! Unfortunately, it didn’t work. I replaced that file in my theme folder (Studio Box by Awesomepress). Any other ideas? Thanks,

Actually, it looks like I replaced the file in the wrong folder. I replaced it in the correct location and it works!!!!! Thank you very much!
