A link to the server could not be established
 

Does anyone know how to fix this? When I'm trying to signup, I get this error.
I've got this problem because somewhere in a php file, the mysql infos aren't configured. Does anyone know where to look to fix that problem?

Have a look at includes/common.php lines 202 and 828...
