Your web request is failing and breaking loading of the plugin, at least in Carbon.
https://tf-crazy.alwaysdata.net/feed.php does not resolve via DNS for me on my client or via my server.
Web request callback raised an exception in 'CRaidController v4.0.7' plugin [200] (Error reading JArray from JsonReader. Path '', line 0, position 0.)
