That could be CB Privacy or CB Conditional. I don't recommend conditioning or allowing privacy on core fields like formatname or avatar as they're used extensively outside of profile to identify users.

Yes, after disabling the privacy plugin this issue get's resolved. I am not sure yet what it exactly means because I never enabled the privacy option for the [formatname] field. I will keep you posted when I figure it out. Going back to the emailing issue. I have tried probably almost anything, disabling plugins, clean install, etc... it keeps doing it. So I started searching the language files and when I found:I decided to test it and change it to:and sure enough this changed the from name of the email but it didn't pickup the username instead it showed it exactly like entered in the language file; [formatname]. So clearly something is not right here. Can you direct me to the actual file that handles this function and maybe send me a copy of yours to see if there is a version issue or maybe a corrupt file?

Well, I didn't mean to make it about the [formatname] substitution. I am trying to resolve the email issue and I was explaining that somehow it is picking upas the from name. Is it suppose to do this? I don't think so. So why is it doing this? Not to forget why is it not adding the user's email address in the body of the email. Which apparently also doesn't work for you.

That's the registration from name within CB > Configuration > Registration. If you've changed that parameter from that language string then it'll use whatever is specified in the parameter otherwise it'll be whatever the language string value is.

I understand that, I only changed it once to troubleshoot it, as a shortcut to find out what value the from name in the email form is picking up. My question is why is it using the 'REGISTRATION_EMAIL_FROM_NAME' language string value. This seems wrong. I don't think CB was designed to use that language string as the from name in the send email form. If I understand it correctly and as mentioned by you in this thread earlier:

The email should be structured as follows.

Subject: SUBJECT
From: FORMATNAME @ SITENAME
Body:

Instead on my CB site it is working as follows:
Subject: SUBJECT
From: 'REGISTRATION_EMAIL_FROM_NAME' @ SITENAME
Body:

I've added a bug ticket for this. I'm not sure why the email isn't substituting in correctly. The extra substitution array looks fine so there's no real reason for that to not work.

Thanks!
