JSON Parse Issue Latest Webpanel

Hi Guys,
I've been receiving an JSON Parse error in Webpanel and I can't figure out whats going on.

The message says this

DataTables warning (table id = 'manageUsers'): DataTables warning: JSON data from server could not be parsed. This is caused by a JSON formatting error.

Can you guys assist me with this problem as I am using the latest webpanel with Hotfix 1

You are posting this at the wrong repo.
This repo is for the 1.1 version of the store plugin.

This is the correct repo of the webpanel:
