Problems with Gallery card, passing validator but not displaying


#1

Trying to test Gallery cards with following URL.
http://staging.utvdev.tibus.net/Galleries/The-Rovers-re-opens/f8cfa0e6-94e1-4342-baa9-592130447377#222858

This page has been passing validator, but has started to fail as of 16:30 GMT, 23/05/2013 (System Error).

Earlier, the page was passing the validator, but still not posting correctly as a gellery.

Any help / tips / things to check gratefully received.
