I have an external link in a rich text widget that is not opening in preview. Our speedbump popup displays, but clicking OK does not take us to the external site. Console is saying: Refused to display in a frame because it set ‘X-Frame-Options’ to ‘SAMEORIGIN’.
Does this have something to do with how preview works?
Just to follow up - Some web sites can have settings that can interfere with displaying them in an iFrame - which is what our Mobile Preview page does. For now you can work around this by removing
?percmobilepreview=true
from the preview URL. We are looking into a permanent fix.
