I have a mod in which I have to give a permission so that one can use a command. After restarting the server, the authorisation no longer works. I have to restart the mod myself so that the authorisation works again. What can I do?

Posting the thread in that plugin's help section might get you somewhere

if your using the command just to give the perm run the command server.writecfg and server.save after and see if it sticks

Thank you for the answer, it all works fine. The permission is given and works. But after restarting the server, I am told that I am not authorised. I then only have to restart the mod, then it works again. This happens after every restart of the server only with this mod. The mod is not maintained but maybe someone looks into the script and tells me what I have to change so that the authorization also works after a server restart. As I said, if I reload the mod after the server restart, the permission works again. It is about Better No Stability
Sorry if I wrote it here, I get on the help page of the mod, no answer

sounds like  Better No Stability is not loading correctly on boot.
looks like This plugin is unclaimed or has no maintainer now.
