Appears to not work on 4.1.1

Hi,

Thank you for the great plug in, unfortunately I cannot seem to get it working.

I followed the installation instructions (using the portfolio template for the page) and made some projects (refreshed the permalinks).

After doing all this, the main page show no content and the individual project pages resolve to completely white pages. (The first time I did it they gave me a 404, but after flushing the permalinks, nothing.)

Have I done something wrong or is there some kind of bug?

The portfolio grid should appear on the page with the template, no?

Thanks.
