I purchased the official theme based on my good experience with md_slider, but so far I have a lot of issues to get this working.

Status:
* installed the demo version of "fashion"
* installation performed using the step - by - step instructions of you documentation and video

Issue:
1. accessing the home page from the local server gives a blank page
2. accessing the home page from remote client works, but is slow.
3. when I log in as admin, the home page no longer works but gives me "500: internal server error". When I deactivate the "page builder" option in the demo page, the error goes away. When I activate the option, the error returns.

It is not possible to learn this theme without the examples, so please help.

Koen.
