When you say “Where is the page”, I’m not sure if you mean “where is the page in the WP manager” or “where is the page stored in the database” or “where is the page visible on the front-end of the website” or “where are the theme PHP files that generate this page?” Answers would vary greatly depending on what exactly you’re asking. Likewise, when you say “how do you display the custom fields in a page”, I’m not sure if you mean “how do I display these fields when I am creating/editing a page in the WP manager” or “how do I print these fields into my theme file for visibility on the front-end of the site” or “how do I reference a field’s value in another page”? Again, lots of variations there, and I’m not sure what you’re asking.
There is an overview video on the plugin’s homepage: https://code.google.com/p/wordpress-custom-content-type-manager/ — it should show you how to associate fields, how to add them to a post-type, and it should point out that the CCTM generates a sample theme file for you as a starting point.
Re the custom fields, please verify that you have in fact STANDARDIZED the custom fields. It is possible to define the fields, associate them with a post-type (e.g. a page or post), and then not display them because they have not been standardized. The built-in post and page post-types are always “on”, but their custom fields may be standardized by the CCTM, or the custom fields can use the default WP behavior. Control this on the main Custom Content Types page.
