sorry i didn’t know. this is my code in the header.php
The code that WPyogi asked you to remove may be below the code that you quoted above. It appears rendered at the top because of an unclosed <script>
tag that looks like Google Analytics code. You may find it like this:
<script>
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).
<<LOOKS LIKE INFECTED, SO I REMOVED MOST OF IT>>
'//www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-40196122-1', 'mammamelocompri.com');
ga('send', 'pageview');
Further, you have an incredibly enormous number of markup errors, i.e., 690 Errors and 133 warnings. So, if you validate your site, most of the problems shall go away.
