I am getting an internal server area when I try and upload 02-herma-elegant zip file. I am following the tutorial and get stuck at this point. I have retired it several times. I am using Chrome on a Mac. Thank you in advance!!!
As message says, issue is server-related. You should first try to figure out what the error is, then you might try to increasing the PHP Memory Limit.

Anyway, you can even use the theme without importing the demo, we have a detailed documentation: http://docs.opendept.net/hemma/
