:( HELP: I am still using Joomla 1.5 and I use K2 Blog for the first time. I created some content for my blog, and everything looks real good except when I add the "read more" into the blog article, I got this error message. And I dont know where to begin to fix the error.

Warning: require_once(/home/mrcfunds/public_html/components/com_mailto/helpers/mailto.php) [function.require-once]: failed to open stream: No such file or directory in /home/mrcfunds/public_html/components/com_k2/views/item/view.html.php on line 317

Fatal error: require_once() [function.require]: Failed opening required '/home/mrcfunds/public_html/components/com_mailto/helpers/mailto.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/mrcfunds/public_html/components/com_k2/views/item/view.html.php on line 317

Can some one please help me with this?
Thanks in advance!
