Same problem here, seems as though something changed on weather underground's side, hoping for an update soon!

Hopefully, its been a year since the last update

I am still attentive, even thou it has been over a year since the last update. (Why fix something that is not broken). I too am getting the same issue on my end. [strike]I will see what I can do to resolve this.[/strike]
Updated version for the new wunderground API has been posted. See the read me at the top of the code before continuing.

Works! thank you :)

can't get !almanac to work here

Also is it possible to show !time as standard and nonstandard (military), I've noticed also that !alerts and alertinfo aren't working. Thanks for all your hard work.
