Try this. It might work for you.
declare
     l_page portal.wwsbr_api.page_record;
begin
     select * into l_page
     from portal.wwv_user_owned_corners
     where siteid = <page group id>
     and id =<page id>;
     -- 0 is disabled . 1 is enabled.
     l_page.haveitemsecurity := 1;
     portal.wwsbr_api.modify_folder(
               p_page => l_page
     wwpro_api_invalidation.execute_cache_invalidation;
     commit;
end;
