Site below:

I have searched ever file and cannot find the “quotes”/text within any of them. Newer to WP, I have built a few sites with Child themes but in no way an expert… trial by error here. I have been through the back end of this site and have missed something……………..

Any and all help would be greatly appreciated!!
