506322 Fix PHP error

Hi, I need a MySQL error fixed immediately! Here is the error: Warning: mysql_query() [/phpmanual/[login to view URL]]: Access denied for user 'nobody' at 'localhost' (using password: NO) in /home/famsol01/public_html/avail/admin/[login to view URL] on line 23 Warning: mysql_query() [/phpmanual/[login to view URL]]: A link to the server could not be established in /home/famsol01/public_html/avail/admin/[login to view URL] on line 23 Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in /home/famsol01/public_html/avail/admin/[login to view URL] on line 24 Warning: Cannot modify header information - headers already sent by (output started at /home/famsol01/public_html/avail/admin/[login to view URL]) in /home/famsol01/public_html/avail/admin/[login to view URL] on line 37 It is on a Centos 5 server. I have attached the [login to view URL] file. I can chat and help you login to the server. Below is how this happened: The domain used for the Nameservers has a dns problem. So until the dns changes in the name servers, I had to have the users add a host file entry for the IP of the server like [login to view URL]~accountname/ on their machines, to direct the computer and browser to the html folder on the site. I've done that. I've also devised a fix so the users have a line in their hosts file for the server. I just need for the database to work and allow them to login! It is 1am here and they have to be able to work in 6-7 hours.
