Installing the theme Art was no problem; however, when I got to the point of installing the demo-data (which I looked forward to working with) all I keep getting are errors – I made sure that all plugins were installed and activated prior to doing so. It is quite frustrating after making this expenditure – almost feels like I made a mistake. Please help me out here.
I have made sure that the plugin was deactivated. I went through the process again following your instructional steps 1, 2, 3, etc.
