Sometimes a client needs to get their forgotten password.  Since we don’t keep those on file, we suggest using the “forgot password” and reset link.

No matter what, it says “please enter a valid email address” once we enter an email that we know should be registered.

We did move things to single sub-domain so that could be part of the problem?

When you move to a single application subdomain you’ll need to make modifications to your “forgot_password” action. Here’s the default code:

Since you no longer make use of subdomains you’ll need to ditch the account lookup and probably change the user lookup to:

So you no longer have the account dependency and can find a user directly from their email address. Let me know if that doesn’t work out.
