Error: Cannot send an empty message

[Awilum]

When I am sending replays to the forum topics, I see this

{"message": "Cannot send an empty message", "code": 50006}[phpBB Debug] PHP Warning: in file [ROOT]/includes/functions.php on line 1868: Cannot modify header information - headers already sent by (output started at [ROOT]/ext/roots/discordnotifications/notification_service.php:328)

I'm also getting this error now. It's just cropped up which is weird as I've not updated phpBB or the extention.

Hi,
Discord has changed their API. Open notification_service.php found in root of the extention dir. Search for $h = curl_init(); and underneath paste this curl_setopt($h, CURLOPT_HTTPHEADER, array('Content-type: application/json'));
