New Install and I get Database error robots.txt? huh

[Wolver2]

Hi I just reinstalled a complete new VB and edited a bit on the styles..
Now my Site crashes very often and I get this error:

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' (11)

MySQL Error :

Verify your mysql servers hostname & set it properly in config.php

Also verify that you set your username & password properly in config.php

[WEBDosser]

Then we need these:
MySQL Error :
Error Number :

With numbers.

[Wolver2]

WEBDosser,

the Fields
MySQL Error :
Error Number :

are empty when I received there error.

Also mysql servers hostname are correct because the website works until i think some bot came along and did something to make it crash.. its very wierd.. after a few min the site was back up though.. happened twice a while ago

The following link has some information on this:

[snakes1100]

MySQL crashing or other wise not responding requires access to the SQL log/Server to find out why its actually not responding.

Before changing any settings in SQL's my.cnf, inspect your logs, if this is a dedicated server/VPS.

[Wolver2]

sadly it is shared hosting.. wished I could see logs somewhere..

Do you have vBSEO or something like it installed?
