Right now I'm stuck on PHP classes, I want to add functionality to a form that is in a class. I make the updates, but have no idea how to view the changes. The do not show up. It sounds like I need to reload the cache somewhere on the server, but the only cache folder I found does not contain this file. The lovely folks who built it for us also didn't tell us who was hosting our site
Here is a pic of what I'm trying to modify, the create.php calls a method in a class contained in Feature.php to display the fields seen below. The Feature.php is not directly included, it's only reference is in a php.php file using require_once. I'm sure it's something really simple, but my lack of understanding of this language makes even my searches impossible because I'm using the wrong terms...

And on a whim, here's a pic of the control panel, anyone recognize this or is this similar no matter who hosts your site?

Any hints or pointers to tutorials, other forums, etc would be GREATLY appreciated
~Thanks
