Re: Help with //
obviously if you have files across your zencart installation that has had changes made to your code then you have a bigger issues to worry about.
in any case comments are dependent on the langauge you are writting in.
<!-- --> for instance applies mainly to any html based coding.
example <!--<h1>wow</h1>-->
// comments out a single line in most serverside scripting langauges, in this case PHP which is contained between <?php and ?> tags
example <?php //$wow = 'wow'; ?>
I hope that makes sense as its off the cuff explanation oversimplified but I would suggest having a professional have a look at what exactly is going on with your site files.
