Hoping you can help. Built this site well over a year ago and all was working fine. Handed it off the to the client and have had very little involvement since. Just yesterday, the client informed me that code started appearing at the top of the site. They apparently have not made any changes in the last few days. Could you take a quick look and let me know what could be causing this? We are running an older version of Atahualpa (3.6.1) and many of the plugins are out of date. I didn't want to do the upgrades until I got an idea of what might be causing the problem.

Click on any of the secondary pages, and you'll see the issue.
Thanks!
