Does anyone know what this database error is?

[funinthesun]

I'm receiving hundreds of database errors!!! I have recently moved my forum to a new server and then upgraded from 3.5.4 to the latest version.

The first database error is:

Invalid SQL:

       SELECT rssfeed.*, rssfeed.options AS rssoptions, user.*, forum.forumid
       FROM rssfeed AS rssfeed
       INNER JOIN user AS user ON (user.userid = rssfeed.userid)
       INNER JOIN forum AS forum ON (forum.forumid = rssfeed.forumid)
       WHERE rssfeed.options & 1;

The second is:

??? ??? ??Lu ??
X-Source-Args: /usr/local/apache/bin/httpd -DSSL
X-Source-Dir: ***********.com:/public_html

Database error in vBulletin :

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
/home/*****/public_html/includes/class_core.php on line 274

The third is:

mysql_connect() [<a href='function.mysql-connect'>function.mysql-connect</a>]: Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
/home/******/public_html/includes/class_core.php on line 274

I really would appreciate any help at all in resolving these errors.

Thank you.
