Advanced WP-Admin Theme

Hello,

I’m working on creating a custom admin dashboard using a control panel theme I found on ThemeForest. I am creating a plugin that changes styling elements and for the most part have all edits I want to make, with the exception of one thing.

***Problem***
Similar to creating custom template pages for a theme, I have defined custom templates to handle certain pages inside wp-admin ( ex. wp-admin/plugins.php ).

I need to get the “Work Area” of admin “Only” – I’ve tried using a simple include:

<?
$site = get_bloginfo('home');
include($site.'/wp-admin/plugins.php'); ?>

And although works, returns ( You don’t have sufficient permissions ) error. The reason is because I’ve been forced to create the “admin theme” as a custom template page that has access to “admin elements” so the user is not under the wp-admin url.

This works:

As show above, this is how I want to display the work area – in the screenshot above, I’m simply using an iframe and have applied visibility:hidden to sidebar, header and footer elements

***My Question***
How can I override the permissions error when using include – or what will be a better option for achieving my goals.

Thanks,
