   The upgrade instructions say not to delete wp-config.php when upgrading (to 2.5.1). The version being upgraded (2.2.3) doesn't have a SECRET_KEY, so should line 13 (defining the secret key) be added to the existing wp-config.php file and uploaded as part of the upgrade?

   I read it before I posted my question. I also read this in the Codex:

   Warning for those performing upgrades: If DB_CHARSET and DB_COLLATE do not exist in your wp-config.php file, DO NOT add either definition to your wp-config.php file unless you read and understand Converting Database Character Sets. Adding DB_CHARSET and DB_COLLATE to the wp-config.php file, for an existing blog, can cause problems — as Ryan Boren says, "your queries will go boom!"

   I don't understand Converting Database Character Sets and I don't want my queries to go boom. I'm running 2.2.3 and want to upgrade to 2.5.1, and the upgrade instructions don't mention anything about the secret key. So do I leave my current wp-config.php alone?

   You can add the secret key to the file all you like.

   Charset and collate are special cases.

   Okay, I think I see. I'll take that as a yes: I can add the new line 13 to the wp-config.php file to define a secret key when I do the upgrade. And my queries won't go boom.

   Many thanks.

   The upgrade from 2.2.3 to 2.5.1 went very smoothly.

   Thank you to the WordPress development team and the forum moderators.

   Otto42, what happens when one inadvertently adds the lines

   define('DB_CHARSET', 'utf8');
   define('DB_COLLATE', '');

   to wp-config.php? (Like myself.)

   Does it influence what happens when you upgrade your database?

   I'm asking this because I have since had issues with several plugins, and text misbehaves if I leave the lines in the configuration file…

   Regarding CHARSET and COLLATE: If you didn't have them before an upgrade, don't add them. If you are installing a fresh install, leave them there.

   Simple as that.

   Which is totally clear Otto42, but what I was asking is:

   What happens if by accident, you put those two items in the wp-config.php of an 'old' WordPress blog and then upgrade the database? Does it affect the database?

    Nothing special happens. Those don't change anything with regards to the upgrade process.

    Thanks Otto42, that helps me in ruling out a cause for issues I have been having since my upgrade.
