If you have Forums and/or Communities (ipk download) for the TouchPad, you’ll notice webOS Nation forums aren’t working. The good news is, there’s a fix for it for Forums AND Communities (now).
The bad news is there’s no fix for it in Communities…yet.
Sadly Forums is dead for webOS 1.x with the change to https. No amount of backup from a working 2.x device and restoration to a 1.x device will help. It was already pretty crippled anyway but this is the nail in the coffin. 🙁
