Admin page links Don't work!

[Guest]

Hi there,

 

I've managed to install ok (after removing safe mode etc from server) however when I get to my admin page but now I have warnings saying

 

Warning: session_start(): open(tmp/sess_7111664ad1ad5819df2ac40f31711709, O_RDWR) failed: No such file or directory (2) in /usr/local/psa/home/vhosts/unique-boutique.co.uk/httpdocs/catalog/admin/includes/functions/sessions.php on line 67

 

Warning: session_start(): Cannot send session cookie - headers already sent by (output started at /usr/local/psa/home/vhosts/unique-boutique.co.uk/httpdocs/catalog/admin/includes/functions/sessions.php:67) in /usr/local/psa/home/vhosts/unique-boutique.co.uk/httpdocs/catalog/admin/includes/functions/sessions.php on line 67

and when I click through to configuration or catalog or any of those it just displays

 

Not Found

The requested URL was not found on this server.

 

Apache Server at unique-boutique.co.uk

 

Any help you could offer would be gratefully received

 

I hope when I get my head round this I'll be able to impart some pearls to others.....
