Site Is So Slow!

[eluser]Jay Logan[/eluser]
So could it be a server issue? I have a dedicated server running cPanel / WHM. Do I need to clear some MySQL query cache? For my auto-loaded libraries, this is what I have:

Code:

$autoload['libraries'] = array('database', 'sessions', 'auth', 'flash',
    'js', 'validate', 'form');

$autoload['helper'] = array('url', 'form', 'app');

$autoload['plugin'] = array();


$autoload['config'] = array();

And what could be causing this error to appear?

Code:

Fatal error: Call to a member function num_rows() on a non-object in /home/caals/public_html/application/libraries/Sessions.php on line 46

I think what I am going to try next is upload the site onto this HostGator account I use for another site. Maybe it's just this dedicated server.
