Indeed I had an old version of WP !
Upgraded it and now Yoast works beautifully

Thank you very much for your help

Thanks webslugger.

I did as you suggested , disabled all plugins. even deleted yoast and added it again. Result is : I have the same fatal error …

As I didn’t read anything like this on the forum, could it be a problem with my theme ?

I am using Clearly Modern 1.7 par Cudazi
