Language Switcher is not working on Magento 2.2.3

[mariamghalleb]

Preconditions

1. Magento 2.2.3
2. PHP 7.0.29

Steps to reproduce

1. I had a Magento 2.2.1 with a website that has one store and two store's views (en and fr)
2. On Stores -> Configuration -> Web , I set "Add Store code to URLs" to "YES"
3. In front office, in the home page 'http://dev4.wetag.ca/) when I change the language it works. But when i'm in a different page such as "http://dev4.wetag.ca/index.php/en/name-tags.html" and i try to change the language from English to French it redirects back to the same URL.
4. Since this was mentioned in here and it said it's been fixed in 2.2.2 I updated the Magento version from 2.2.1 to 2.2.3 and the problem is still there.

Expected result

1. The store view changes when a user tries to, whether in the home page or in any other page on the website.

Actual result

1. The store view only changes in the home page, in any other page, when the user tries to change the store view (the language) it doesn't work, it redirects back to the Home page with no errors.

Too sad that such core functionality does not work since 2.2.1...
