(sorry the bad lenguage, but i'm italian!)
When I try to acces at the administration panel of my Wordpress blog, after the login, appear:

Fatal error: Allowed memory size of 16777216 bytes exhausted (tried to allocate 19456 bytes) in /www/vndv.com/c/h/e/checazzate/htdocs/wp-admin/includes/user.php on line 382

What can i do? Thanks
