Hi all, I've just intalled k2 on a site built with joomla 1.5.22, the installation went good, and the category page is good as well. But opening an item I got this error:

Warning: require_once(/web/htdocs/www.site.it/home/components/com_mailto/helpers/mailto.php): failed to open stream: No such file or directory in /web/htdocs/www.site.it/home/components/com_k2/views/item/view.html.php on line 305 Fatal error: require_once(): Failed opening required '/web/htdocs/www.site.it/home/components/com_mailto/helpers/mailto.php' (include_path='.:/php5.3/lib/php/') in /web/htdocs/www.site.it/home/components/com_k2/views/item/view.html.php on line 305

I've surfed the web a bit to find a solution to fix that but I've found nothing at all.. just an unsolved topic..

Do you have any advice for me?
I'd really appreciate solutions that do not include the upgrading to joomla to the 2.5...

Thanks everybody

Hello Giovanni,

If you don't want your site hacked you should upgrade to the latest J! 1.5 release.
1.5.22 is really old and will cause you problems.

Btw site.it is a Wordpress site!! Please provide us with a link.
