Confirmed Working with 1.5.6c! Thanks Developers and Support!!!

***Only issue I noticed is that "config.xsell" must be installed last.
When I copied that file before anything else in the "YOUR_ADMIN" folder, My Zen Kart Admin portal would return the error HTTP 500 Bad Request.


After installing each file, I make sure to refresh a random page on my website and refresh the Zen Kart Admin (YOURWEBSITE.COM/YOURADMIN).
This helped my find the issue much faster than in the past :)
