Not opening login page for admin

Nice product you have. I was also looking for something simple.
The problem I have is that I cannot open the admin pages.
What I have tried sofar. Normally I am using Hiawatha as my webserver https://hiawatha.leisink.net/ . Also very simple but secure. The setting to use the CMS are WebsiteRoot = /var/www/reboot-cms/web. Hiawatha uses different rules than .htaccess. I played around with these rules but I could not open the adminpage(s). (http://server.local/admin).
So I decided to install reboot-cms on Apache. The only thing I did was to put a line in 000-default.conf: <DocumentRoot /var/www/reboot-cms/web. I typed in: http://mail.local/admin and got http://mail.local/admin/login (The requested URL was not found on this server.) All the other pages works perfect.

What did I do wrong? Do you have any advise?
Many thanks in advance.

Please try to set "/var/www/reboot-cms/" as the document root. Does that work?

Got the same problem. I need to install in a subfolder on apache webroot.
The login page doesn't show telling its causing too many redirect.
And moving everything to the root (even if it's not the way I need to use it) throw a fatal error completely.
It's on PHP 8.3.14.

For now, installing in a subfolder is not supported, sorry. The CMS must be published as Web-ROOT ("/"). However, a subdomain would work. As I don't need this use case, it is unfortunately not a top priority for me personally. But, it is OpenSource, so feel invited to change this situation. 🤗

It works for me if I use a subdomain instead of a subdirectory (PHP 8.4 on Apache).
