Why am I getting error "Account:Account is required"

[Vineeth Rajan Nair]

I faced the exact same error after installing tempo. So what you need to do is simple,

Go to tempo-> administration-> tempo account-> Tempo accounts configuration section-> UN-CHECK the default field configuration.

There's no way of knowing why you're getting this.  What have you configured that requires it?

We can help you work that out if you could start by telling us where you get this error.  What, exactly, are you trying to do when it appears?
