**Description**

When enabling multiple languages in Open edX with the Indigo theme, the language switch dropdown generates an incorrect URL. The issue is caused by the following line in the `header.html` file:

**File:** [`tutorindigo/templates/indigo/lms/templates/header/header.html`](https://github.com/overhangio/tutor-indigo/blob/release/tutorindigo/templates/indigo/lms/templates/header/header.html#L95C1-L96C1)

```auto
value="${reverse('session_language')}"

```

**Issue:**

- The `session_language` URL is incorrect.

**Fix:**

- It should be replaced with `update_language` to work correctly:

```auto
value="${reverse('update_language')}"

```

Would appreciate a fix in an upcoming update! 🙂

Hi. Feel free to open a PR against release branch [GitHub - overhangio/tutor-indigo: An elegant, customizable theme for Open edX](https://github.com/overhangio/tutor-indigo). You already have a proposed fix, you should do the honor of adding it 🙂 .
