Hi,
We have several sites on a multisite structure, and almost all of them use Google CSE. However, some of these websites display the error "Refused to display the error "'http://www.google.com/cse?cx=...' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'". This behaviour happens only for a couple of sites. I have compared Google CSE settings, and they are identical. How can I fix this issue?
