Hi,

I have migrate my site from one host to another (same provider), I have created the db, imported all the data, correctly configure config.php & database.php but I can't access the site at the new location, I have enbaled the debug fonction and I get the following error message :

```php
A PHP Error was encountered
Severity: Warning

Message: require_once(/home/picsoob/www/posbeta/system/core/compat/mbstring.php): failed to open stream: No such file or directory

Filename: core/CodeIgniter.php

in fact, **/home/picsoob/www/posbeta/system** is not correct and should be **/www/posbeta/system** but I have no idea where to change it since it's correct in config.php : **$config['base_url'] = 'http://www.picsoocloud.com/posbeta/';**

it seems that BASEPATH have a wrong value.

any help will be very appreciated,
thanks in advance,
Domi.
