This Piwik code in injekt_footer

Hello ,
Have a problem.
This Piwik code in injekt_footer can be seen on every online page
even though I had deleted in basic settings. Before closing Body Day.
in basic settings. Before closing Body Day, the Piwik entry is not available.
Not available in the DB.
I have to delete it
because Google makes problems
can not delete, because not seen in basic settings. Close window before Body Day.
I do not know what to do.
Do you have any idea?

Yesterday I found the error in: templates / base / footer.html

there found the code.

I have deleted.

everything ok now.

But thank you for your fitback
