After upgrade, sends me to install.php

Something wrong with my wp-config.php (I copied over the database settings per instructions)?

Did you also copy over the setting for the $table_prefix in wp-config.pyhp?

Michael, looking at my old wp-config (which I backed up), here it is in its entirety (w/ specifics x’d out):

<?php
// ** MySQL settings ** //
define(‘DB_NAME’, ‘XXX’); // The name of the database
define(‘DB_USER’, ‘XXX’); // Your MySQL username
define(‘DB_PASSWORD’, ‘XXX’); // …and password
define(‘DB_HOST’, ‘XXX’); // 99% chance you won’t need to change this value

/* That’s all, stop editing! Happy blogging. */

define(‘ABSPATH’, dirname(__FILE__).’/’);
require_once(ABSPATH.’wp-settings.php’);
?>

I don’t see any setting for table_prefix to copy over!

In the new (current) wp-config, there’s this:

/**
* WordPress Database Table prefix.
*
* You can have multiple installations in one database if you give each a unique
* prefix. Only numbers, letters, and underscores please!
*/
$table_prefix = ‘wp_’;

But that’s just how it came — I didn’t change anything.

Use phpMyAdmin and look at your database. Look for the posts table that would hold your posts. If the name of that table is wp_posts, then your $table_prefix would be ‘wp_’, if the name of the posts tablee is xyw123_posts, then your $table_prefix would be ‘xyw123_’

If the posts table is called ‘posts’ then you should use
$table_prefix='';

I got this sorted out. Thanks!
