Re: Members area Login with permissions!

Hi,

thank you for answering! I do have a session_start() in config.php.
For now there is no redirection as you mentioned, but it should display a link to 
the corresponding next homepage based on user level, which it does not do at this time!

I thought <div class="message"> was only a class? I already have a $message variable that do display:
$message = 'The username or password is incorrect.';

When it comes to separating the code, I think this is a good idea, afraid this will mess the code further up to do at this point?!
 
Regards
