I have an operating version of a WordPress system (version 2.9.1) running with MySql (version 5.0.27). In the process of setting up a new server to host my databases, I installed the latest version of MySql (version 5.1.42), and migrated the wordpress database to the new server using the MySql migration tool.
However, after getting everything set up (creating the necessary MySql users, assigning rights, etc.), the WordPress app will not connect with the new database server, and returns an HTTP 500 error.
Any ideas on how to get this runnng?
