Random Kicks

So my problem is whenever someone drags and drops an item out of their inventory, it kicks them with the message "Internal server error". This has just started after I downloaded the backpack plugin, but in the console the error doesn't say anything about it.

This is just an annoying bug, please help

If it just started after you installed the plugin, then try uninstalling it and see if the error is still there. It could be that the plugin is outdated or its not compatible with another plugin you have on the server.

 

Still broken.

 

Are there any errors in the console, like any from when it starts to when the players get kicked? Try posting the whole console log from when the server starts to when it kicks.

 

When it says 'internal error' there will be something in your server log. Pastebin your log here

YES there is an error from sentry

I was making a sentry and I typed /sentry health armor on accident.

It made an error in the console.
