There are two places where blog settings in WordPress are stored: the main WordPress configuration file, and the individual blog’s wp-config.php file. The main WordPress configuration file is located at wp-config.
php on the root of your WordPress installation, and the individual blog’s wp-config.php file is located at the root of the blog’s WordPress installation, but inside the wp-content directory.
If you have a multisite network of WordPress blogs, then each blog’s wp-config.php file will be stored in a different directory on your network’s server.
If you want to change a setting for all blogs on your network, you need to change it in the main WordPress configuration file, and then update each blog’s wp-config.php file with the new settings.
The location of individual blog settings in WordPress can be a bit confusing, so here are some tips to help you find them:
1. To view all of your blog’s settings in one place, go to the “Settings” menu item on your blog’s main page (the page that appears after you log in to your blog).
2. To view all of your blog’s settings in one place, go to your server’s “wp-content/plugins/WordPress/settings/”directory and open the “wp-config.
php” file for your blog there.
3. To view all of your blog’s settings in one place, go to your server’s “wp-content/themes/WordPress/settings/”directory and open the “wp-config.
php” file for your theme there.
4. To view all of your blog’s settings in one place, go to your server’s “wp-admin/update-options.
php” file and open the “General Settings” section for your blog there. (This is where you can change many of your blogging preferences.).
5. To view all of your blog’s settings in one place, go to your server’s “wp-login.
php?action=profile&user=username&password=password&blog=blogname&site=siteurl&edit=1″file and open the “User Profile Information” section for your user there (this is where you can change many of your blogging preferences).
