Bare with me whilst i read 1250 lines to find which "random messages" you're referring to. Could not load 'plugins/BungeePexBridge.jar' in folder 'plugins' Could not load 'plugins/NoSwear.jar' in folder 'plugins' Remove those plugins from your plugins folder too^
1) ServerPinger has no plugin.yml, remove it 2) BungeeHub is not available for the mc version your using, remove it 3) BungeePexBridge ^^ 4) NoSwear is wrongly compiled, remove it 5) CoreAPI, cannot connect to the database and has other errors 6) PermissionsEx has a corrupted database, might be because of switching version 7) skQuery is not available for the mc version your using I cannot find what is spamming ARMOR_STAND in the end, but the plugins above cause a lot more spam.
