So I just upgraded to WordPress 2.3 and POW, my site stops working, dead. Did they change the instructions? It used to be that you just make sure you don’t overwrite your wp-content or config.php files. Nope, that’s still the same. Quick, to the Apache logs!
[client 220.127.116.11] PHP Fatal error: Cannot redeclare get_terms() (previously declared in /var/www/html/burrowowl.net/wordpress/wp-includes/taxonomy.php:447) in /var/www/html/burrowowl.net/wordpress/wp-content/plugins/Similar_Posts/similar-posts.php on line 848, referer: http://burrowowl.net/wordpress/wp-admin/options-permalink.php
ah-ha! One quick find-and-replace later, we’re back in business.
