Problem with sending Application

Hi,

I have seen this topic 2y ago but no answers so i ask again because it happens to me right now ??

When i apply the form i have this message :

“Error sending notification message, but dont worry, We saved Your data securely. Thank you.” and cannot receive the email.”

Do you have any clue to help me ? Here’s the page : https://curium.world/en/poste/technicienne-analyses-physico-chimiques-en-laboratoire-mobile/
