I installed an SSL Certificate, then edited my .htaccess file:
# -----------------------------------------------------------------------------------------------
# 9. If you only want to allow HTTPS, uncomment the RewriteCond and RewriteRule lines below.
# -----------------------------------------------------------------------------------------------
RewriteCond %{HTTPS} off
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
by uncommenting out the Rewrite lines.
Now I get 404 error pages when I try go to any .../processwire-master/<pagename>/
This includes my admin page at .../processwire-master/processwire/, so i can't get into my admin.
What else do I need to do?
