Hi, I thank you very much for your message.
I have received a message from wordpress informing me that it is an extension that cause the problem (Paypal for Woocommerce) and they proposed me to launch the recovery mode.
I did that and i could recover my WP admin console.
I have desactivated the paypal extension and one by one activated the others extensions and also reactivated jetpack.
I didn’t need to go inside php files, luckily !But i keep your informations preciously.
Thanks a lot for your message again.
Pat
