"/> appearing on the website frontend
Issue:
Go to your wordpress website admin panel ( probably wp-admin/admin.php?page=psp#Google_Analytics ) and here at the end of the page, there is the option "Google Webmaster Tools".
The value in the option input should only contain your google code ( content entered in Google Webmaster Tools box ) not the entire metag (<meta name="google-site-verification" content="content entered in Google Webmaster Tools box" /> )
