Impossible to add a new language

After a clean install of Polylang (v 3.3.1) on Wordpress (6.1.1 up to date), I can add any language via the 'Add a new language' button.

The error message is : impossible to add an new language.

It is impossible for me also to add a new language via polylang config panel.

How did you solve this problem ?

Solution

  • I finally find why : the database contained old data.

    I de-install polylang
    I backup my site
    I install WP-Optimize and clean the database completely
    I install polylang

    No more error when adding a new language.
