depoll

I managed to fix this by replacing a method in functions.php:

// theme widget: Twitter
function fusion_TwitterWidget($args){
 extract($args);
 echo $before_widget;
 print $before_title.__('<a href="https://www.twitter.com/'.get_option('fusion_twitterid').'">Twitter posts</a>','fusion').$after_title; ?>

 <?php
 $username = get_option('fusion_twitterid');
 $limit = get_option('fusion_twitterentries');
 if($username<>'') {
  $feed = file_get_contents("https://search.twitter.com/search.atom?q=from:" . $username . "&rpp=" . $limit);
  $feed = html_entity_decode($feed);
  $clean = explode("<content type=\"html\">", $feed);
  $amount = count($clean) - 1;
  print '<ul id="twitterupdates">';
  for ($i = 1; $i <= $amount; $i++) {
   $cleaner = explode("</content>", $clean[$i]);
   print '<li class="entry">';
   echo $cleaner[0];
   print '</li>';
  }
  print '</ul>';
 }

 echo $after_widget;
}

Note: I also made the title of the widget link to your twitter id’s twitter page :). Hopefully this helps!
