ambiguous plugin messages mean that you have multiple different jar files that represent the same plugin, and the server doesn't know which is the correct version to load, so it just flips a coin each time. This can make your server work, then not work, then work then not work at random if the versions are different enough, and if ie the new one adds a config entry that the old version launching cant read and errors out, or then the new one loads up and that setting has been removed when the old one resaves its config out.. Identify the jar files that you need to keep, remove the other.

MobDisguise is always a error-throwing plugin, as it depends very specifically on the build version of the server to work, and if there is not a version specifically for the version you have, its not upwards-compatible by default.

Unknown Dependancy message: ProtocolLib
This means that the plugin has a dependancy (requires another plugin) in order to run properly - in this case, it needs ProtocolLib -- and needs the version specific to the build of your server.
