I installed the latest version 2.5.1 tonight and it broke a site. I now get the following error message on every page while the plugin is enabled:
Fatal error: Call to undefined function mb_detect_encoding() in /home/foo/public_html/wp-content/plugins/lightbox-plus/classes/shd.class.php on line 1251
I'm sure you will take a look when you get a few seconds as I can see you are busy tonight so I'll say thanks in advance.
LBP is an ace plugin so thanks for making it and supporting it.
