Modules > Site > Site Controller has method index which i want to show when navigating to localhost/bb/

And in my routes i have:

Code:

$route['default_controller'] = 'site/site';
$route['404_override'] = '';
/*
| -------------------------------------------------------------------------
| CUSTOM ROUTES
| -------------------------------------------------------------------------
*/
$route['static/program_search'] = 'site/site/program_search';
$route['static/search']      = 'site/site/p_search';
$route['(:any)']            = 'site/site/index/$1'; // Pages Routes

Bu this $route['(:any)'] then won't allow access to localhost/bb/admin which is the CMS i have built. Which obviously needs to be accessibile.
via this route: $route['admin'] = 'sessions/index';
