Hi, sorry if I don't explain myself well, this is my first post like this.

Two weeks ago I took a break from my server as I was going on vacation, and when I came back I found that ProtocolLib and Lib's Disguises are no longer functional

Server Specs: Minehut, 1.17.1, paper

Upon starting it again the Libs Disguises files don't contain any data and restoring to old backups does not work

I tried updating both plugins and it did not work, Minehut had a separate issue where my older backups were for some reason irretrievable, whenever I try to restore to old backups it just says "could not validate backup" Minehut just did a series of large updates so I think this is why I'm unable to simply restore to a previous backup

As Lib's Disguises is dependent on ProtocolLib, I looked through the logs and found that ProtocolLib is being disabled upon startup and then due to it being disabled Lib's Disguises is disabling itself as well, in the logs it told me to create a ticket here so that is what I am doing.

If there is anything that you can do to help I would truly appreciate it, I lost over 300 disguises.

Thank you,
CaptRexCT7567

Here is the transcript of the relevant logs for both ProtocolLib and Lib's Disguises
If you need any more of the logs feel free to let me know I can send the whole transcript.

[21:16:55] [Server thread/INFO]: [LibsDisguises] Disabling LibsDisguises v10.0.44

The error message clearly indicates that plugin reloaders should not be used with ProtocolLib. It seems you used a plugin reloader and encountered the following error:

[21:16:47] [Server thread/ERROR]: ******************************************************
[21:16:47] [Server thread/ERROR]: *** ProtocolLib does not support plugin reloaders! ***
[21:16:47] [Server thread/ERROR]: *** Please use the built-in reload command! ***
[21:16:47] [Server thread/ERROR]: ******************************************************

If this is the case, please close the issue, as this behavior will not be addressed.

I'm not sure what a plugin reloader is and havent to my knowledge ever installed one, Minehut recently did a massive update to their servers, could they have installed one of their own or something like that? I could post my plugin list if that would help!

Thank you

Could you please provide a list of the plugins you are currently using? Additionally, does this error occur immediately upon restarting the server from scratch, or does it happen after executing a specific command or action in your server hosting panel? Any additional details you can provide would be helpful in diagnosing the issue.

Could be related to the Java version but is highly unlikely. Have you already tried the latest dev build of ProtocolLib maybe that fixes it: https://ci.dmulloy2.net/job/ProtocolLib/lastSuccessfulBuild/

It happens immediately on restart or starting from hibernation

I have not added or removed any plugins in the last six months, this issue started 2 weeks ago
Minehut just did a parent company data transfer and all of my old backups are now invalid and protocollib and libsdisguises are now broken, they said all they can do is restore to the most recent backup which still has this issue.

I did find today that after they transferred the data to the new parent host, the version of Java for the server was automatically updated from Java 16 (which is what 1.17.1 needs) to 21.0.3 which is too new. Is it possible that the only issue is the wrong version of Java?

Thank you so much!
