I just installed this template into a fresh zc155 and I'm experiencing a couple issues.

First, when adding products to the shopping cart (or just clicking on Shopping Cart link), I receive this message:
An unknown response null: :text/html; charset=utf-8: :SyntaxError: Unexpected token m was received while processing an ajax call. The action you requested could not be completed.
Also, on the backend, I receive a persistent message at the top my admin in a green box:
Enabled Responsive Sheffield Blue Configuration Menu.
To try to resolve conflicts, I started going thru the files supplied by the template, comparing and merging with zc155 originals.

Some of this work is simple. For instance, it seems pretty clear that admin/layout_controller.php needs to be merged into zc155. Other comparisons seem to indicate that the template file should be discarded entirely in favor of the zc155 original. For instance: /includes/classes/Mobile_Detect.php

Other merges are downright messy and it's unclear to me how to proceed (/includes/classes/split_page_results.php).

So to answer this question:

Thanks
I'm inclined to say maybe you should wait for a zc155 update to this template?
