Not displaying properly (only small portion of it is displaying)

Not displaying properly (only small portion of it is displaying). It was working fine, i don’t remember when it started not working.

fyi: recently i copied my site to another host. it was working fine on new host too. i also made some changes to improve page speed as suggested by pagespeed insights.

fb likebox plugin is also behaving same. [look at bottom right corner]

my site: https://lagatar.com
