|These are some guesses since I haven't heard much feedback about it|
1. See if the Archive page element is activated.
2. If it is, delete it and then re-Add it.
3. If that doesn't work, check Settings-Archiving.
4. Change the Archive frequency (temporarily) to something else just to see if that will wake up the system. Click Save Settings at the page bottom.
Let me know if it works out. I need to find out if I'm full of moonbeams to make these suggestions.
