PHP - Strict Standards Help

I'm making forums at the minute and everything is going well, apart from these stupid errors that I can't seem to get rid of for the life of me. It is frustrating me so much! I've looked through the code and cannot find anything wrong.   The first error appears at the top of my forums whenever you're logged in about strict standards. This is what the error says:     Line 6 of viewthread.php is - require('../structure/forum.thread.php');;   Here is the code of the thread::canView() and thread::canView() that is located within my structure.   thread::canView function below

    public function canView($id, $username, $powerLevel)

     {

I would like some expertise of some one that could help me on this i m getting the following error, on the code i m developing:
