now that you mentioned it i have no idea why this is not included in vivvo's htaccess as standard seeing that it's a must for most websites.
creating a robots.txt file will not work without editing your htaccess file first so here it is.
even if you have robots.txt in your root directory no one will be able to see it and you will get your 404 page if you try to access it.
solution:
Add this line to you htaccess file
Code:
RewriteRule ^robots.txt$ robots.txt [L]
then in robots.txt add this (if you want to stop search engines from indexing your print pages
Code:
User-agent: *
disallow: /*.html?print$
Hope that helps
