I decided to upgrade to WordPress 2.1, and I have to say: it all went very, very smoothly.
The only trouble I had was with Subscribe to Comments. Although version 2.1 of this very cool plugin had been released, and it was said to work with WP 2.1, it didn’t. You got an error like “ This problem was fixed, as the author kindly pointed out in the comments, so if you download Subscribe to Comments now, all will be fine.
Warning: in_array() [function.in-array]: Wrong datatype for second argument in /var/www/joostdevalk.nl/blog/ wp-content/plugins/ subscribe-to-comments.php on line 438“.
For history’s sake: Fixing this was actually quite easy: on line 438, right before
get_post_meta(, add “
(array)“, and it all worked again smoothly. Kudos to Everton Blair for this fix.
I’ll update this post with any other trouble I run into after this upgrade.
