Pb e-mail information sent to a group at each new event

Hi Franky

I have been using a hook, in the function.php file of my theme for 2 years as the example you show in your documentation.
It worked until about 3 weeks ago (I don’t have a lot of event programming at the moment) but today it didn’t work, on both active and local sites. The event is created via EMEFS. Is it due to a plugin or WP update? I don’t know. Can you check and tell me if you have any idea ?
I detailed the hook on
