Bad Kitty

I just installed the LDD Directory plug-in and its amazing! BUT, when i worked through submitting a new entry from the front end as a test user, it came up saying No Kitty Bad Kitty… I had a google and its something to do with a NONCE setting? I’m not a developer so am pulling a blank here.

We launch in one week and need help!
