I am using two localhost installs of WP 3.5.1. One of these has Custom Post Type UI v0.7.2 installed. The second install doesn't have the plugin installed; instead I 'Get Code' from installation 1 and paste the generated code in the functions.php file of installation 2.
The post type is configured to support tags in its taxonomies. But the tags metabox only shows up in the install that has the plugin. In the second install (where I add the code manually) everything else seems the same, except that the 'tags' metabox doesn't show.
How can I get the metabox to show?
