sorry, didn’t want to make a mess in the other thread.
I always receive a 403 Error when I want to install a Demo Content.
Attached a Screen Shot.
Can you let me know what this could be?
Sorry to hear of the problem you are having.
I have tested it on my test site and it’s working fine for me using latest version of Jevelin theme.
Please make sure you are using below latest version of theme.
