 * I tried to install this plugin, but I got this info:
 * “Plugin could not be activated because it triggered a fatal error.”
 * I use 3.0.4 WP with PageLine’s Platform theme. I have these plugins installed:
 * Akismet
    Breadcrumb NavXT External Videos SlideDeck for WordPress – Slider Widget
   TubePress Twitter for WordPress Vodpod Video Gallery VodPod Videos Widget
 * Any idea what could be wrong?

 * Hmm, I deleted two vodpod plugins and the WP stats plugin installed (I don’t 
   know if the problem was related, I just didn’t need the other plugins anyway).
   Now, however, I still cannot get the plugin working. I’m trying to put in the
   API key and it gives me this error:
 * `Warning: require_once(/home/pslnewsy/ftp/wp-includes/class-IXR.php) [function.
   require-once]: failed to open stream: No such file or directory in /home/pslnewsy/
   ftp/wp-content/plugins/stats/stats.php on line 645`
 * Fatal error: require_once() [function.require]: Failed opening required '/home/
   pslnewsy/ftp/wp-includes/class-IXR.php' (include_path='.:/usr/local/lib/php')
   in /home/pslnewsy/ftp/wp-content/plugins/stats/stats.php on line 645
 * Could someone help me please?

 * Try [downloading WordPress](http://wordpress.org/download/) again and delete 
   then replace your copies of everything **except** the `wp-config.php` file and
   the `/wp-content/` directory with fresh copies from the download. This will effectively
   replace all of your core files without damaging your content and settings. Some
   uploaders tend to be unreliable when overwriting files, so don’t forget to delete
   the original files before replacing them.
