When I click "Edit" for any comment, I get this error in the admin panel

Warning: AdminUI_general::require(/home/hari/public_html/b2evo/inc/comments/views/_comment.form.php) [function.AdminUI-general-require]: failed to open stream: No such file or directory in /home/hari/public_html/b2evo/skins_adm/_adminUI_general.class.php on line 510

Fatal error: AdminUI_general::require() [function.require]: Failed opening required '/home/hari/public_html/b2evo/inc/comments/views/_comment.form.php' (include_path='.:/usr/share/php:/usr/share/pear') in /home/hari/public_html/b2evo/skins_adm/_adminUI_general.class.php on line 510

The correct path seems to be:
/home/hari/public_html/b2evo/inc/comments/_comment.form.php
