One homepage missing

Hello all,

I’m using Polylang to make my blog available in 6 languages. Globally it’s working very well but I have one issue that I have not managed to solve.

Default language is FR which means that the default homepage is the following:
https://www.laurentwillen.be
each other version of the home page is using the following structure:
https://www.laurentwillen.be/%5Blanguage%5D

It works for all languages except for English while there is no difference in the configuration of that language.

Example:
https://www.laurentwillen.be/nl/ works
https://www.laurentwillen.be/es/ works
https://www.laurentwillen.be/en/ doesn’t work and returns a 404 which is then redirected to the default home in French.

Do you have any idea of what goes wrong ?

Thanks
Laurent
