Thanks a lot :)
This solved the user level issue, I can now login with different user levels and get displayed with a link to the corresponding index-pages.
But I am now facing a new issue regarding this; when I am entering the URL's of the corresponding index-pages I do get access to the
corresponding index-pages without having to login at all!! Is there a way to prevent this form happening?
And is there also a way to hide the
URL's that goes beyond www.url.com, e.i. www.url.com/index_admin.php?
Regard
