The link shown on the My page for a wiki incorrectly uses /mod/ouwiki/view.php?wid=<id from the wiki table> and yields the error "A required parameter (id) was missing" when clicked.

The fix is to modify /mod/ouwiki/lib.php line 433 to use the course module id:

$CFG->wwwroot.'/mod/ouwiki/view.php?id='.$new[$wiki->id]->cmid.'">'.
