Looks like that docs link has been "moved", the most directly applicable (to ZC 1.5.5) is: http://docs.zen-cart.com/Developer_D...n_sanitization
Sorry, I meant to mention the link didn't work... I found it easy enough

Somewhat surprisingly, it's not too difficult to apply the desired sanitization once the regex stuff at the bottom is better understood (currently doesn't have "straight" words about what it allows/removes, just identifies the "code" of what it does).
At the moment, I'm playing around off-line, so it's quick and easy to disable it... I've also enabled logging and once I get my head around the instructions and what's in the logs, I should be able to nut it out
