Error on logout an error has occured the request page cannot be found

Joomla 1.7 Error message – If you modified your default.php file for your template default login file ie: /html/mod_login/default.php – you might get an error message that says:

    An error has occurred.
    The requested page cannot be found.
    404Category not found
    If difficulties persist, please contact the System Administrator of this site and report the error below.

In this case, all you need to modify is the redirect in the Login module Module Manager.  For example once user logs out I want the user to be redirected to back my homepage.

1.  Login to your Joomla 1.7 administrator panel.

2.  Click on ‘Extensions’, ‘Module Manager’,

3.  Click and edit your ‘Login’ module.

4.  Under Basic Options, set a redirect page in the value for – Logout Redirection Page.   For example:

    Logout Redirection Page =  Main Menu – Home

5.  Save the Login module.

Now you can refresh your website.  Test the logout function and it should work.  On logout it should redirect you back to the default homepage.
