Or simply remove this from your code:

                //Mark, If an user is Super Admin.
        if ( Auth::check() ){
            $isOpen = $user->isAdmin();
        }

[behlul]

I did. but this time I got 500 internsl error.
Where can i download 2.0 versiyon?

[shahzainqadir1]

The best way to do that

//Mark, If an user is Super Admin.
if ( $user->isAdmin() ){
$isOpen = $user->isAdmin();
}

[shahzainqadir1]

This code is needed for admin to review pending courses.
It should be

//Mark, If an user is Super Admin.
if ( $user->isAdmin ){
$isOpen = $user->isAdmin();
}

[x8smile]

This course should be this:

//Mark, If an user is Super Admin.
if ( Auth::check() ){
if ( $user->isAdmin ){
$isOpen = $user->isAdmin();
}
}
