Is that file you're trying to include even on a remove host? If not you should include it locally like this, and you might not have that problem in the first place
<?php include '/var/www/web58/html/nydomain/wordpress/link.php'; ?>
You would have to figure out the right path to the file. The first part up to /var/www/web58/html/nydomain should be correct as can be seen by that error message you posted earlier.
If the file IS on a remote host then you would have to try CURL instead of include, see the URL I gave you, or get your host to allow you to include remote files by setting PHP to allow_url_fopen On
