I designed a blog theme for a client, and tested it and everything was fine. When i installed it last night, anytime you click on a post title or comments, it gives this error:
Fatal error: Call to undefined function get_post_type_object() in /home/tsj/public_html/blog/wp-content/themes/thematic/library/extensions/dynamic-classes.php on line 103
Any ideas? I saw another post about having to upgrade to wordpress 3.0. On the dashboard it says that she has the latest version (but it actually says 2.9).
I'm hoping to get this issue resolved today- and advice would be fantastic!!
