 * Hi reader!
 * I have just moved my blog to a new URL.
    Everything is fully OK, working and 
   all, but if I go into any of my posts, I have a warning message at the beggining
   right before the body of the text saying: Warning: strip_tags() expects parameter
   1 to be string, array given in (root, changed it)/html/wp-includes/formatting.
   php on line 631
 * Now line 631 is the following:
 * 629function sanitize_user( $username, $strict = false ) {
    630 $raw_username 
   = $username; 631 $username = strip_tags($username); 632 // Kill octets 633 $username
   = preg_replace(‘|%([a-fA-F0-9][a-fA-F0-9])|’, ”, $username); 634 $username = 
   preg_replace(‘/&.+?;/’, ”, $username); // Kill entities
 * I figured that if I switch off YARPP then this message disappears, but I would
   really want to use YARPP since I was happy with the plugin so far.
 * Any idea what to do to get rid of the messages.
