Re: Validator Issues... I'm stumped
Unfortunately Zen Cart is a can of worms when it comes to handling HTML entities. There are just so many places in the code and plugins where it's overlooked. Plus if you start to sort them out, it has an impact with onsite search. Having a consistent policy and enforcing it seems to have been put in the too hard for too little gain basket for many years.
So so you need your own site policy. I do my best to use 'and' not '&' wherever possible. Then I just wear the validation issues caused when & has to be used in brand names and product codes.
Zen Cart 1.5.5e, PHP 5.3.29 MySQL 5.5.42
