How to change URL

I've changed the URL of my site what file or BD do I need to change?

Have you changed it in your hosting records? That depends on the host and the panel you're using.

In Dolphin it's a little easier:

inc/header.inc.php - make sure you set the permissions to allow you to change the file.

$site['url']               = "http://mysite.com/";

The following may be changed if you've also moved servers.

$dir['root']               = "path to/index file/";  -  Often  "path to/public_html/"; (Only if you've changed something)

$db['host']                = 'localhost';   - Usually localhost

$db['sock']                = '';

$db['port']                = '';

$db['user']                = 'user  name';        if you've changed it.

$db['passwd']              = 'xxxxxx';           if you've changed it.

$db['db']                  = 'xxxxxx';                if you've changed it.

Reset your permissions and try.
