i'm getting this error when i launch the catalog/index.php

 

Fatal error: Cannot redeclare tep_href_link() (previously declared in /homepages/40/d25729297/htdocs/catalog/includes/functions/general.php:24) in /homepages/40/d25729297/htdocs/catalog/includes/functions/html_output.php on line 15

 

 

line 15&16 (html_output.php):

  function tep_href_link($page = '', $parameters = '', $connection = 'NONSSL', $add_session_id = true, $search_engine_safe = true) {

   global $request_type, $session_started, $SID;

 

 

does someone know where the problem is?
