The word NOT appears as last line and reports

Hi I am new here and a real amateur
I installed Piwik on our website through our internet service provider
A) opening my index page I see the word Not as last line. See What do I have to do
B) looking at the reports I do not see any visitors. Am I excluded as a visitor?
Tkvm in advance for your answers

Can you please post a screenshot showing the problem of NOT ?

Maybe it is more simple to look at the page
It is the very last line down just under the words "nar boven"
Below I give you the codes of the last lines

Tkvm in advance for your answer

Besides the question above:
I know that somebody looked at the site but nothing is to see in the visitors overview.
What do I do wrong?
Tksm again for your answer in advance
