Display lang code as http://www.domain.com/examplepage/?lang=fr

Hi,

I’m using the Polylang plugin to have the website https://www.iraiser.eu/ in French and English. But for the moment, the Q & A plugin of WPMU DEV https://www.iraiser.eu/suggestion-box/ask/ is adding /fr/ or /en/ to the URL ; so everything is broken.

To solve that, they say that on WPML : you can use something like https://www.iraiser.eu/suggestion-box/ask/?lang=fr”.

Do you have a suggestion or could it be possible to have this lang code ?lang=fr with Polylang, at the end of the URL?

Thanks in advance,
