Problem (FabledSkyBlock)

Hi! I wanted to translate the FabledSkyBlock plugin in the file, after trying to save changes, an error occurred.

Thanks for help.

Version:

PaperMc 1.12.2

Plugin:

FabledSkyBlock (songoda) fabledskyblock-2.2.1 (01.04.2020)

Error:

Przepraszamy, wystąpił błąd!

ID: 57e6bb232a2df2dc-WAW
Error: 403                 

ref.

As there are no "arguments in the file" it works, but when I paste it translated, then this error occurs. I can't translate plugin and message.

I think the reason for this may be too many lines in this file, but I'm not sure. The file has over 5k lines if not more. At this time, I have removed the plugin from the files and decided to replace it with another one until the problem is resolved. I would have to reinstall.
