Server logs

.

Please try with just AntiPopup installed and let me know if anything changed.

Btw, logs say that 1.20 injector is used while you said that you are running 1.19.3, can you confirm the version with /version?

For default server working fine.

Add your plugins back one by one and see which one causes it.

Yeah. I'm still wondering why this exact exception occurs. I faced it in a personal plugin. NoSuchElementException: packet_handle with a println showing packet_handle 1 line above so it shouldn't happen.

I've seen these issues occur out of the blue with reloading (not with this plugin). Did you reload the server or reload individual plugins using /reload, Plugman/PlugmanX or ServerUtils?

Antipopup is a packet based plugin, and packet plugins tend to break when reloaded so i wouldnt be suprised if that was the case.

+1, this happened to me too

I have no idea but if somebody has a clue please reopen the issue.
