Thank you for your help. It resolved the issues that I was seeing.
I wonder, however, if you have any issues relating to the new release of WordPress, 3.4? My dev site (https://www.dev.curnow.org/) was upgraded and Cookillian seems to have stopped functioning but my non-upgraded site is fine (https://www.cunrow.org). Have I tweaked one to many things on the dev site?
Thanks in advance.
