Access control problem with Panel and Views

Thanks a lot for the answer. Sorry, i don't understand what do u mean by question "This is node data".

My idea is for everyone to see all the content as i said, and i am not using any access control modules.

I was looking into directory modules/node, file node.module, and the only code with the row that you wrote was this, i don't know if that is the place where i should look???

if ($grant['grant_view'] || $grant['grant_update'] || $grant['grant_delete']) {
        db_query("INSERT INTO {node_access} (nid, realm, gid, grant_view, grant_update, grant_delete) VALUES (%d, '%s', %d, %d, %d, %d)", $node->nid, $grant['realm'], $grant['gid'], $grant['grant_view'], $grant['grant_update'], $grant['grant_delete']);
      }
    }
  }
}

/**
 * Rebuild the node access database. This is occasionally needed by modules
 * that make system-wide changes to access levels.
 */
function node_access_rebuild() {
  db_query("DELETE FROM {node_access}");
  // only recalculate if site is using a node_access module
  if (count(module_implements('node_grants'))) {
    // If not in 'safe mode', increase the maximum execution time:
    if (!ini_get('safe_mode')) {
      set_time_limit(240);
    }
    $result = db_query("SELECT nid FROM {node}");
    while ($node = db_fetch_object($result)) {
      node_access_acquire_grants(node_load($node->nid));
    }
  }
  else {
    // not using any node_access modules. add the default grant.
    db_query("INSERT INTO {node_access} VALUES (0, 0, 'all', 1, 0, 0)");
  }
  cache_clear_all();
