I've installed easy fancybox and got it working - but only with the default 2012 theme, and not with my custom theme.
I can see in the html that the fancybox scripts are loading in, but when clicking the images they simply show the jpg's instead of the in a fancybox modal.
What on earth is happening? The site isn't live, but if you go to http://cbDOTtawd.co.uk/celebration-cakes/ you'll see a page in question (replace the DOT in the url with a period character, as it's a sub domain of http://www.tawd.co.uk - hope this makes sense - don't want it spidered yet.)
Thanks in advance!
