Error opening lesson

In my access I am not able to open the lessons.

Note: No lessons work, I've tested it in several browsers.

Example: 

https://www.chess.com/lessons/roots-of-positional-understanding/the-art-of-restraint

There is a known bug with some Mastery lessons for members without English as their language and Content Language set as My Language and English. 

Until that is fixed, if you switch to English, you'll be able to access lessons that have the problem.

Perfect. I changed the language and it started working right away.

Thank you! Problem solved.

Depuis plusieurs semaines quand je clique sur leçon rien ne se passe j’ai accès aux exercices d’après les leçons . Comme je ne les ai pas eu je ne comprends pas comment les résoudre. C’est frustrant. Avant je n’avais pas ce problème.

merci pour vos retours sur ce sujet
