Upgrading to 2.0.0
The main changes introduced in this version are layout changes (UI/UX, graphic interface).
The only required difference with older versions is a new plugin, System - Invoice Manager, which must be installed in order for Invoice Manager to work properly in Joomla backend.
Please make sure to install and enable this new plugin, which was not found in previous version of Invoice Manager (v. 1.4.9 and below)
