Hello, I need a little help. When a user writes a comment on an ad, shouldn't the administrator be notified somehow? And the second question, which is a bit more problematic, in the admin panel when I have to approve that comment, it gives two errors, but the comment is still approved. I don't understand why. I'm attaching screenshots of the errors.

I'm using the Zara theme, I think it's related to that.

Thank you, I'm waiting for a reply

Go into that file and line above add
$email = '';

It worked, it doesn't give the errors anymore. But I still don't understand how to make it notify the administrator when someone adds a comment, in the sense that they know they have a comment to approve. In the comment settings, the notifications section is activated, but the administrator receives the email after approving it.

Thx!
