Forum plugin error
 

Whenever i am trying to import a plugin i am getting this error

Warning: require_once([path]/includes/class_template_merge.php) [function.require-once]: failed to open stream: No such file or directory in [path]/admincp/template.php on line 1286

Fatal error: require_once() [function.require]: Failed opening required '/home/indianci/public_html/board/upload/includes/class_template_merge.php' (include_path='.:/usr/local/php52/pear') in /home/sami/public_html/board/admincp/template.php on line 1286

Any one know how to fix this?
