WARNING! The latest version 2.1 of Lightbox Plus, the popular WordPress image viewing plugin, does not work satisfactorily with WordPress 3.0!

After just updating from v1.6.something to v2.1, I could neither access my website nor the WordPress admin area. I always got an error message relating to a certain PHP file in the plugin’s installation folder. So I manually migrated back to v2.0 (which has no reported failures according to the plugin’s website), now everything runs as it should again.

Here’s the plugin’s website: http://wordpress.org/extend/plugins/lightbox-plus/
