Since this morning, nobody can subscribe to my newsletter in my blog. In French, they get this message after taping their email : Vous ne pouvez pas vous inscrire avec l’adresse de messagerie que vous avez saisie, veuillez contacter l’administrateur du site. (You can’t subscribe with your email, please contact the website administrator.)

I’ve done nothing on my website so I am wondering if the last automatic plugin update is the issue and how to solve this problem… Thanks for you help.
