Hi Catherine,
I just looked at your theme and it has a bug that is not related to the solution I provided you. It’s probably a plugin or another modification that was created previously, which I can provide information about but only for a technical person that would know how to use this info to solve the issue.
I would suggest you to take a look at your previous changes and plugins to see what is the issue there.
You should take a look at our Testing for Conflicts page, which provides some tutorials on how to test to see where the problem is coming from.
My Best Regards,
