 * Try replacing line 90 of hits.class.php, which should be:
 *     ```
       $crawler = $current_browser->Crawler;
       ```
   
 * with:
 *     ```
       if( is_object( $current_browser ) ) {
       	$crawler = $current_browser->Crawler;
       }
       else {
       	$crawler = false;
       }
       ```

 * Also found out when this happens.
 * This happens only, when a Plesk system checks the wordpress websites on his own
   server. So the server its own ip connects to the website to do the check.
 * But you might already knew this.
 * Tnx i changed it.

 * Could this be the case? the error is gone from my logfile? But maybe this is 
   causing it? Possible?
