What's wrong with my code in wordpress?

Question

I have a problem and I am hoping you could help me.

This is the error I get when I want to open my wordpress page:

Parse error: syntax error, unexpected $end in /web/WebSites/d/v/i/e/viennaphotobookfestival.com/htdocs/wp-content/themes/Divi/includes/social_icons.php on line 52

I don't know what's wrong in the codes, can you help me? Thanks in advance!
