Can't start server after installing plugins

I have just set up etherpad lite on my VPS and everything worked fine out of the box. However, no matter what plugin I tried to install it seems to crash the server instantly after a restart. Uninstalling the plugin through npm uninstall solves the problem, but doing this would mean that I can’t use any plugins. I’m running Ubuntu 16.04 LTS, npm version 3.9.3, and nodejs version 6.2.1.

Here are the error messages:

Thanks for your time!

The problem has been introduced by this commit: https://github.com/ether/etherpad-lite/commit/835bca7967473dc21fa6de4eb56357c92e4f43a3

fs.statSync can’t be used synonymously to fs.exists. fs.statSync throws an exception if the file/direcotry does not exist. See https://blog.raananweber.com/2015/12/15/check-if-a-directory-exists-in-node-js/

Using the master-branch of etherpad instead of develop seems to work for me.
