parent.php missing

Dear,
Im currently experiencing an issue when I try to write an article via the front end, I get the following error:

Warning: require_once(/home/luclie/le-lievre.com/components/com_easyblog/models/parent.php) [function.require-once]: failed to open stream: No such file or directory in /home/luclie/le-lievre.com/components/com_easyblog/models/blogs.php on line 16

Fatal error: require_once() [function.require]: Failed opening required '/home/luclie/le-lievre.com/components/com_easyblog/models/parent.php' (include_path='.:/usr/local/lib/php:/usr/local/php5/lib/pear') in /home/luclie/le-lievre.com/components/com_easyblog/models/blogs.php on line 16

I looked for the file parent.php and it indeed doesn't exist. Did I screw up something or is there something missing?

Thanks for the help.

Regards,
Luc
