php & MySQL Errors

[neverdo]

I am running PhpBB 3 and a Wikimedia on my website: http://neverdo.exofire.net (Cossacks). Neither of them seem to be working. I have checked the Up Down Services list (http://forums.x10hosting.com/free-hosting/13706-x10hosting-services-up-down.html) and the MySQL seems to be online, however I receive errors when I attempt to load the wiki and the phpBB forum.

phpBB - http://neverdo.exofire.net/phpBB3/index.php
Wikimedia - http://neverdo.exofire.net/wiki

phpBB 3 Problem:

General Error
SQL ERROR [ mysqli ]

Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2) [2002]

An sql error occurred while fetching this page. Please contact an administrator if this problem persists.​

Wikimedia Problem:

Fatal error: Call to a member function selectRow() on a non-object in /home/neverdo/public_html/wiki/includes/User.php on line 759​

About the phpBB3 error, the SQL database server info is correct, such as mysql.x10hosting.com instead of localhost as the path to the database server, and the Mediawiki error appears to be a messed up PHP error to my eyes. By the way, what server are you on? It's Cossacks that I believe is having an SQL problem.

I'm on cossacks, that must explain it. Also, the phpBB forum was working before.
