Anyone ever solve the Wemo Switch Issues?

I’m still not able to connect to Wemo Switches using the built in apps. All I get is an error “Failed to save page: fistPage” in app and in the live logging I get this error:

9:11:05 PM: error java.lang.reflect.UndeclaredThrowableException @ line 178

Can anyone help me? I read there’s a template for a self managed WeMo Connect template but I can’t find it anywhere.
