Hi RavanH.
Thanks for the reply.
When I activate the YouTube option (have played with a number of the YouTube settings) then clicking on the YouTube thumbnail does nothing, and also seems to disable the script so that image galleries can’t be opened. Disabling the YouTube option takes the user straight through to the YouTube page when clicked.
Have disabled PrettyPhoto … I only have Easy Fancybox running site-wide as far as I can tell. I don’t understand why this wouldn’t work?
