Blank page trying to login Admin

Hello, I am new to Shopware, I’ve installed SW 6 (clean) on my hosting service to a subdomain. The install completed with only a coupe of minor issues (resolved)

  1. The admin login page displays no problem
  2. Admin login seems to work but result is black page.

Is this because I installed on a sub domain

The expected URL should be …but that does not work

What I am looking for is to get into Admin section

The front end is another problem

Any help is always appreciated

the URL seems of there is hashtag symbol after admin# is it suppose to be there?

Any help here someone must have experienced this issue, how did you resolve it.
