 * Same: “The plugin does not have a valid header”
 * It appears in the backend immediately after installation/activation. I’m using
   WP 3.0.3 without other plugins…
 * Thanx in advance for your support!

 * Hi, version 2.0b of the Content Sort plugin is now published, lots of news and
   no longer need for special templates!
