XF 1.5 canonical URL

[SimonaB]

Hello everyone, I need help. You have to set the URLs as "canonical".

I need to exclude duplicate pages generated by the forum, such as this:
https://www.wywebsite.it/forum/members/sampi13.68901/recent-content

<link rel = "canonical" href = "https://www.wywebsite.it/forum/members/sampi13.68901/" />
How can I do? Thank you all.
