Guys would appreciate some help on this as i'm tearing my hair out or what is left of it.
Ran through install process... got to the web part, did everything EXACTLY as per the instructions. Browsed to the page and got this.
Server platform is Windows 2012 R2 / SQL Server 2014 / IIS.
Filestorage permissions set correctly?
Yep found it, issue with a typo on the filestorage path in the connection settings config file.
