The infos I added on Comment devenir une légende 2016 worked, thy were added but now I can't add the cast for the episodes (which I'm part of. I brings me to IMDB pro and blocks me there every time
You need to add the cast to the specific episodes, for example http://www.imdb.com/title/tt5500632/?ref_=ttep_ep1 scroll to the bottom of the page, hit edit page, cast, add credits, continue and submit the names from here.
I hope this helps. Let me know if you have any other problems.
