tplContactForm Chunk

<p>Имя: </p>
<p>Email: </p>
<p>Телефон: </p>
<p>Сообщение: </p>

when sending, it swears at an error in the email field, although it is excluded from validation
at the same time, messages arrive in the site admin panel.

Answer 1

Which is strange.
How do they get into your admin? Are you processing letters or is a separate ajax request flying? The snippet code shows that no one saves "to the admin".
Do you have any more JS code that is tied to validation?? Could this be his contribution?
Alternatively, replace the email field name with, say, email2, what happens?
Additionally, try setting emailFrom and emailReplyTo
