I tried to turn on advanced permissions using:

define('PERMISSIONS_MODEL', 'advanced');


And after adding this to site.php the pages that I have created apart from homepage the rest give the following error message...

Page Not Found
The page you are looking for might have been removed, had its name changed, or is temporarily unavailable. Please try the following:

If you typed the page address in the Address bar, make sure that it is spelled correctly.
Click the Back button in your browser to try another link.
Use a search engine like Google to look for information on the Internet.


The pages were working before I typed in the advanced permissions code into site.php so I think It might be because of what I did can someone tell me how to fix this please thanks.
