Restoring database and config.inc.php

Hi,
I have my ojs installed and I was using it normally, but I dont know why my database bricked. So I
have re-installed my mysql and restored it from my backup but now I am
having problem with it. I changed the config.inc.php file but I cant
find the problem. Every time I try access my site It redirect to
“install page” in another hand in my Config.inc.php is set “Installed =
On”.
You can see it at: http://www.ceres.ufv.br/ojs/
and if I try access another page like Acesso there is a error:
Warning: mb_internal_encoding(): Unknown encoding “” in /var/www/ojs/lib/pkp/classes/core/String.inc.php on line 70

ADONewConnection: Unable to load database driver ‘’
Any guess about what it can be?
best regards

Hi @xicaooo,

If you’ve restored a copy of your database from backup, then leave “installed = On” and make sure your database configuration in the “database” section is accurate.

I wonder if you don’t have a typo of some kind in your configuration file. Try comparing it carefully with config.TEMPLATE.inc.php to see if there’s an inadvertent change introduced. (I’d use a tool like “diff” to do this.)
