  • I had the same problem because it was conflicting with another plugin – Easy Content Types – that I am using. I fixed by going to the file ultimate-taxonomy-manager.php and commenting out the line where it flushes the cache, like so:

    //$wp_rewrite->flush_rules();

    Everything worked fine after that.

    I lost 1 hour because of that.
    No one should be allowed to call $wp_rewrite->flush_rules() outside of activation/deactivation hook.
