What is the id_manufacturer parameter for?
A page with this code (page A) appears in the code of another page (page B), however, it does not appear anywhere else. The problem is that page A has a broken link.
Is it possible to delete this line of code or can it harm the site in any way?
< div class="manufacturer" > ==$0
<a href="//onlineticketoffice.example.com/en/example?id\_manufacturer=0"></a>=$0
