Slack webhook fails with 411 username

[kasperbrandenburg]

in Slack.php:62 the CURL 'username' => Util::getSiteName(), attribute seems to cause problems. I created a standard webhook to a slack-channel, and got a 400 Bad request back. I Changed it to "webhookbot" and it startet to work.

I tested this out with a numeric sitename and it appears to work fine. Do you have more details?

Writing 411 as text direct in the curl-post() method also works. Its only when the attribute is populated. I tried to grab the actual output by doing print_r($curl); This is some of the data i got back

Hmm, can you try dumping the POST data being passed to Slack. My guess is that getSiteName() is returning null (though that shouldn't happen).

@kasperbrandenburg is this still occurring?
