redirected you too many times

Is /page-eng/ a page or a site of a multisite installation? It should be the later one.

it’s a rute than contains another independiente instalation of wordpress.

Have you activated the plugin on the target WordPress installation (= /page-eng/)? That could cause the infinite loop. The plugin must only be activated on the redirecting site (= /).

No, the plugin is only instaled on the root.
The folder /en/, that contains another wp intalation, doesn’t have this plugin.

If /en/ is the installation then the configuration should be

en=/en/

No.
I have 2 independent wordpress, one in the root and another in one folder called “en”. I have 2 databases.
The plugin is instaled only in one of them, in de root wordpress.
Can I make a redirect using this plugin to any URL, for example, https://hosting.com/en/ ??
I need this:
Default works like this: https://hosting.com
If english is detected-> https://hosting.com/en/

The supported use case is:
/ = only for redirecting
/de/ (if German is detected)
/en/ (if English is detected)
…

Examples are https://www.monkkee.com/ or https://www.vostel.de/.

It’s not supported that the redirecting instance has content.

Well, I have tried a lot of things.
If I write in default:/
And then mapping: en=/en/
I get error “redirected you too many times”
If I write -> en=/something/ I get same error

Write in default: /en/

If I write in default /en/, what do I write in mapping? es=/ ??

es=/es/

On the right side of the equals sign there must not be /. That causes the redirect loop.

es=/es/ doesn’t exist in this wordpress.
Should I create this rute using another plugin?
default: /en/
mapping: es=/es/
?

You mentioned “es” above, maybe a typo? Anyway, you only list the languages and sites you have in the mapping field.

Sorry I dont’t understand you.
My web es hosting.com and is a wordpress in spanish.
When browser is english, I need to redirect to another location, por example /en/ or another url. /en/ is an example. If I write en=/something/ redirection doens’t works.
You say: write in default /en/
So I need to crate a mapping for spanish. But spanish is the home, the rute is “hosting.es/”.
How can I write the mapping?

As I said before

The supported use case is:
/ = only for redirecting
/de/ (if German is detected)
/en/ (if English is detected)
…

Examples are https://www.monkkee.com/ or https://www.vostel.de/.

It’s not supported that the redirecting instance has content.

hosting.es/ must not have content. You need a site “hosting.es/es/” if you’d like to use this plugin or look for another solution.
