Silverstripe on subdomain in a subfolder not working


I am trying to place silverstrip on a subdomain in a subfolder, for ex:

But all I get is a 404 not found error, does this even work?

It should work, yes. Can you provide any more information about what you’ve tried, how your environment is configured, etc.?

Hi DorsetDigital, what I use on that subdomain is a login system, that after login redirects to the subfolder.

This is the .htaccess file at the root of the subdomain:

# suppress PHP errors from displaying in the browser
php_flag display_startup_errors off
php_flag display_errors off
php_flag html_errors off
# enable PHP error logging
php_flag  log_errors on
php_value error_reporting -1
# prevent access to PHP error log
<Files PHP_errors.log>
Order allow,deny
Deny from all
Satisfy All

Probably I am missing something.

I have the same problem?
Fresh install… all put into /silverstripe
i can call /silverstripe/install.php but no styling at all
If i click button re-check requirements it is taken back to the root /install.php so does not go into the silverstripe folder.
What do i wrong?

BTW. ive put into public .htaccess

RewriteEngine On
RewriteBase '/silverstripe/'

sorry guys… decided to rebuild all sites into Wordpress.
If it was the first time i totally had to rebuild the sites after an update ok… but it is not!
Loved SS for years… sorry
