Subdirectory URL without trailing slash causes 403 error

[erJasp]

When putting October into a subdirectory, it only works when adding the trailing slash to the URL (http://localhost/october/). The URL without trailing slash (http://localhost/october) will display a 403 error or the directory listing.

To fix this issue, add the following to the .htaccess file:

RewriteOptions AllowNoSlash

Info: https://httpd.apache.org/docs/current/mod/mod_rewrite.html#rewriteoptions

When installing to a subdirectory, a RewriteBase should also be set in the .htaccess. It would be great if this could be automated during the install (since it's one of my most heard questions when installing a CMS), but this might as well be just a little note in the installation doc.

Thanks for this, I have updated the .htaccess seed file, since the .htaccess file is treated like a config file, it should be updated manually. (The update process will not touch this file)

New contents:

<IfModule mod_rewrite.c>
    <IfModule mod_negotiation.c>
        Options -MultiViews
    </IfModule>

    RewriteEngine On

    ##
    ## Directory Listing attempts
    ##
    DirectorySlash Off
    RewriteOptions AllowNoSlash

    ## Redirect trailing slashes

    RewriteRule ^(.*)/$ /$1 [L,R=301]

    RewriteRule ^ index.php [L]

    ##
    ## Standard routes
    ##
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ index.php [L]

</IfModule>

All fixed on my end.
