$path='/hsphere/local/home/c34727/foros.fotoviaje.net/'; Is it correct?
How can I know it? :) It depends on what is given by getpwd() function.
<?php include ('http://foros.fotoviaje.net/addon_1stpagenews2.php');?> is it correct?
Dealing with PHP include means your subforum should be on the same server as the primary site. This add-on can not be included like you did, via HTTP request.
