Hello/Hi/Greetings,

I installed plugin Contact Form, but only registered users can send contact form.
To unregistered users, the plugin indicates successfully sent, but nothing really reaches the administrator's inbox.
I do not understand where the problem is: In Plugin? In opitions Piwigo?

Many thanks for you suppor

Piwigo version: 2.8
PHP version:
MySQL version:
Piwigo URL: http://
