I’ve taken a look at your Google Analytics code and everything seems to be fine.
The only thing i noticed is that a page-wrapper div is not properly closed, but I doubt that would affect Google’s code search.
To fix the closing page-wrapper div, go to wp-content/themes/elvyre and open a file called footer.php.
Go to about line 84 where it’s written:
<?php if ($pi_theme_options['website_layout'] == 'boxed'): ?> <!-- .page-wrapper start --> <div id="page-wrapper" class="clearfix"> <?php endif; ?>
Modify the upper code so it looks like the following:
<?php if ($pi_theme_options['website_layout'] == 'boxed'): ?> <!-- .page-wrapper end --> </div> <?php endif; ?>
Save the file and upload it to your server replacing the current file version.
Check out if Google still reports that the script is not installed correctly.
