Wow! It is a blooper from me!
I’m sorry 🙁
Anyway, you gave me the path to the origin of the problem. The site comes to me from other people, with a plugin installed, and now I realized it is a very old plugin, I will replace with yours.
The old plugin: https://es.ww.wp.xz.cn/plugins/advanced-custom-fields-contact-form-7-field/
Thank you!!!
