More info that you have to collect and share back
In config.php what is DB host? an IP or localhost?
If localhost it means on same server as code.
IF localhost, what access do you have to that server? Other than Moodle .... tools like cPanel? ssh? (mysql client).
Where are you hosted and how? Example: OVH,Rackspace, other ... package? Shared hosting? Dedidated VPS? Wouldn't hurt to share what operating system also.

In other words, read the forum documentation first!
