Server Version

git-bukkit-ab38754 (i cant upgrade cause of server providers)

i have no acces to that 

What other plugins are you running?

craftconomy3 , dynmap 3.0.1 , minepacks , permissions bukkit 2.5 , sethomes 1.2.3 , timber 1.0.7 vault worldedit bukkit 7.1.0

What is happening?

i cant set up a shop or buy from it and command like csacces displays this massage " an internal error accurred while attempting to perform this command"

What did you expect to happen?

idk that is works

Please provide any additional info below

idk xD

One thing: The plugin requires at least Spigot, it will no longer run on CraftBukkit (which hasn't really been updated in years now anyways). Either update to Spigot or Paper or downgrade the plugin.

Beyond that I can't really tell you much without the server log.

I have the same problem! I switched to Spigot as was said! I have the server version 1.16.3 (i.e. the latest)! The log outputs this:

@justman10000: You are not running the latest development build, please test with that. Also please test if the issue persists through a full server restart, the /reload command might cause issues sometimes.
