Two wordpress instances in different directories and same domain

Help
1

1. The problem I’m having:

I am migrating from shared Apache web server to VPS Caddy server.
On my former server I was running two separate Wordpress instances. Each running in a folder. The folder structure was:

https://example.com/spanish
https://example.com/english

So based on the Accept-Language var, the root .htaccess ( https://example.com) chose where to take the user. If language was Spanish (ie. es-ES), then the user was redirected to https://example.com/spanish. If not Spanish, then it takes him to the default https://example.com/english

I used .htaccess files to achieve that in the old hosting. One in the root path, another in the /spanish path and another one in the /english .

Here is the content of those .htaccess files:
[1] PrivateBin

So I am trying to replicate the config into Caddy with no luck. Even though I managed to make the redirect apparently fine. But the way is processing it when is gets to the proper directory does not seem to be ok as I get a 500 error.

The Wordpress instances have both set the siteurl and home as below (same as it used to be in the former hosting):

siteurl: https://example.com/english
home: https://example.com/english

siteurl: https://example.com/spanish
home: https://example.com/spanish

2. Error messages and/or full log output:

* Request completely sent off
< HTTP/1.1 500 Internal Server Error
< Alt-Svc: h3=":443"; ma=2592000
< Content-Type: text/html; charset=UTF-8
< Server: Caddy
< Status: 500 Internal Server Error

3. Caddy version:

v2.8.4

4. How I installed and ran Caddy:

a. System environment:

VPS - Debian 11 bullseye

d. My complete Caddy config:

example.com {
        # Set the root directory
        root * /var/www/mainsite

        # Redirect to /spanish if Accept-Language header starts with 'es' and URL doesn't start with /spanish or /english
        @redirectToSpanish {
                not path /spanish* /english*
                header_regexp Accept-Language ^es
        }
        redir @redirectToSpanish /spanish{uri} 301

        # Redirect to /english if URL doesn't start with /spanish or /english
        @redirectToEnglish {
                not path /spanish* /english*
        }
        redir @redirectToEnglish/english{uri} 301

        # Handle requests to /spanish
        handle_path /spanish* {
                root * /var/www/mainsite/spanish
                php_fastcgi unix//run/php/php7.4-fpm.sock
                file_server
        }

        # Handle requests to /english
        handle_path /english* {
                root * /var/www/mainsite/english
                php_fastcgi unix//run/php/php7.4-fpm.sock
                file_server
        }
}

What’s in your Caddy logs though?

I note a few things:

  • You’ve got canonical site URLs in WordPress that include the language URI prefix.
  • You’re using handle_path which strips the prefix before routing the request.
  • You’re using root * /var/www/mainsite/<language> to establish which site files should be served.

This strikes me as a little odd. WordPress expects the prefix, but you’re taking it out.

Kinda like saying to WordPress, no, the client didn’t actually request either of your sites, but serve/process the files from the English site, just trust me. (Or Spanish).

I don’t know if it’s the cause of your issues, but it seems incongruent. I wonder if handle_path is actually the behaviour you want or if you just want handle.

I think your config could be written tremendously more efficiently.

example.com {
  @language path /spanish* /english*
  handle @language {
    root * /var/www/mainsite
    php_fastcgi unix//run/php/php7.4-fpm.sock {
      # Override try_files to keep the root index file boxed in
      try_files {path} {path}/index.php {path.0}/index.php
    }
    file_server
  }

  handle {
    @spanish header Accept-Language es*
    redir @spanish /spanish{uri}
    redir /english{uri}
  }
}

Thanks both for your quick replies.

@Whitestrake I barely have experience with Caddy. This is actually my first time playing around with it so sorry if the previous code did not make much sense.
So I updated Caddyfile with your code. However, I keep getting error 500 from Wordpress.

I debugged & got this log:

10:53 → Spanish browser

@francislavoie Thank you. capture_stderr showed the issue (the Wordfence plugin)

@Whitestrake thanks so much for the code, it just works great.
