 * Anyone use this plugin?
 * I am trying to use it so WP doesn’t like my categories like
 * Cat1
    Cat2 Cat3
 * And instead like Cat1 – Cat2 – Cat3
 * When I load the plugin I get the following errors:
 * Warning: Cannot modify header information – headers already sent by (output started
   at /homepages/39/d87590790/htdocs/nickhates.us/wp-content/plugins/wp-nice-categories15.

 * It would appear the plugin does not work, (it is the 1.5 version)
 * Any suggestions to fix this or perhaps another way to list my categories this
   way?
 * Thanks

 * Do you mean [this one](http://txfx.net/2004/07/22/wordpress-conversational-categories/)?
   There’s a newer version, which I mentioned in [this post](http://wordpress.org/support/topic/33423).
   I’m using it with no problem since the latest release came out.
 * However, the error you’re getting is a common one. See the codex:
