(Update 12/19/2009 - 1024 PST - Looks as if my main database is still in mySQL 4.0 format although GoDaddy support 5.0. Probably never had need to upgrade DB since I moved there. Support email sent in on how to upgrade database)
Hmmm. Upgrading your Wordpress installations is typically a part of good system management, but when trying to install the latest version of Wordpress 2.9 this morning I received the following error.
Downloading update from http://wordpress.org/wordpress-2.9.zip.
Unpacking the update.
The update cannot be installed because WordPress 2.9 requires MySQL version 4.1.2 or higher. You are running version 4.0.27.
I am not sure if this effects all of GoDaddy's shared servers or just mine, but it could effect a lot of people if their default install of mySQL is this version.
What are you experiencing with Wordpress 2.9 installs on shared servers?
