I think you and Peter are right. Somehow mail variable which is taken
its value from a form field is assigned a None value.
Here is the hosting.html part of the code that include the form
variable mail
<form method="post" action="">
<input type="text" name="mail" value="Ποιό είναι το email σου?"><br>
<textarea name="comment" cols="40" rows="5">
Σχολιάστε ή ρωτήστε με σχετικά....
</textarea><br>
<input type="hidden" name="page" value="hosting.html">
<input type="submit" value="Ρώτα">
</form>
But as you can see it has a default value of "Ποιό είναι το email
σου?"
So how can be of a NoneType ?

You mean the web server's last error log messages for the error.log
file?
