Hi maybe you know why i see this information? I add GA code in nop-widget.
"Move the tag inside the head.
We have detected that the Google Analytics tracking code is outside of the
section on this page. This decreases the likelihood that the tracking beacon will be sent before the user leaves the page.
One of the main advantages of the asynchronous snippet is that you can position it at the top of the HTML document. This increases the likelihood that the tracking beacon will be sent before the user leaves the page. We've determined that on most pages, the optimal location for the asynchronous snippet is at the bottom of the
section, just before the closing tag.
Solution: Ensure that you add the Google Analytics tracking code onto this page before the closing tag."
Maybe you change this plugin in NOP3.6?
