Object of class stdClass could not be converted to string...

Yes, sorry, I just really haven't had time to do anything with the module lately. I have asked for anyone to help maintain, but no one seems to be interested.

I think I have seen this before, but I'll have a look, and also I'll have a browse through the other bug reports, as it sounds familiar.

Hmm, it is happening when going through and collecting possible field key values.

In the admin, what do you have selected for the name field?

Do you have any special user modules or profile modules enabled?

It might help to try disabling all non-standard modules and seeing if you still get the error. Then enable each one until you find the error appears. If I know what other module might be conflicting, then I can try to come up with a fix so that they don't conflict.

I might try installing content profile to see if that causes it.

The error is definitely occuring here:

function campaignmonitor_campaignmonitor_field_key_values($user) {
  $out = array();
  $out = (array)$user;
  foreach ((array)$user as $key => $value) {
    if (is_array($value) && $key != 'role') {
      $out[$key] = implode('/', $value);                   // LINE 455
    }
    elseif (in_array($key, array('login', 'access', 'created'))) {
      $out[$key] = date('c', $value);
    }
    elseif ($key != 'roles') {
      $out[$key] = $value;
    }
  }
  $out = array_merge($out, _campaignmonitor_get_user_tokens($user));
  return $out;
}

Basically what the above function does is go through and get all possible tokens for the name field. Maybe there is some sort of field type in content profile that is causing this line to not like the value.

Is this causing any error in the actual functioning of the module? Like is it causing a subscribe or unsubscribe to fail?

Sorry, it has been a long time since I have had a look at this.

Is this still an issue? Just want to make sure before going further into the issue again.

I just got this error also. Not sure why.

Subscribing.

From what I can tell, the error comes about when the user's user name contains a space. So I have a user: "Test" or "TestUser" and it works fine.. but for a user called "Test User" with the space, I get this error... would that make sense?

I still can't cause this. I've tried a user with a space, and I still don't get the error.

Is anyone with some drupal experience getting this? It would be great if you could put some sort of watchdog statement above the line I've marked as 455 that prints out the key and value. That might give me an idea of what is causing it. Seeing what didn't cause that issue and what did.

I'm still getting this. I'm not collecting Name at all, only email.
