Have installed all folders and files as according to the manual but unfortunately the server still wont start with the discord plugin installed, same error result.
i was having the same issue. do not use the files in the english manual as it is only version 15.0 you need 15.0 with shared 0.7.0. look on the first post the download links are run together so i had to mess with the link a bit but it is now working with 15.1DiscordPlugin-0.15.1.zip
