I encountered some problems:
 * 1) JavaScript pages suddenly won't update no matter how many times I pushed the purge button and the clear cache button.
 * 2) Different languages appeared on JS review box and the forum activity box. In the Dev Wiki, those boxes sometimes shows Russian, Dutch and Polish.
