Ok, so what I did is:

1) Uninstall MeeCast
2) delete te MeeCast dir from ~/.cache/
(it's name currently on my phone is com.meecast.omweather
3) go to Warehouse, search for a Meecast install, Enable repo first, then install
4) after install, it had installed version 0.7 but soon I have got the long forgotten Update Available icon, updated it and got version 1.1.12, and all started working.

I'm using OpenweatherMap and GisMeteo, but I'd say all the others are also working.

Hope this helps
