www domain is breaking the page

I do not even know where to start looking for the problem.

I have a website: http://krs.solar. I also specified in the html that this is the cannonical url.

when you go to www.krs.solar or http://www.krs.solar the images do not show and the logo animation is higher.

What can be the issue? In the inspector, you can see that the images are loaded. I also replaced the images location with absolute path to see if this is the problem, but it is not.

I am using bootstrap 3, jquery and bodymoving. This is my htaccess:

ErrorDocument 404 /404.php
<IfModule mod_rewrite.c>
    Options -Multiviews
    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{HTTP_HOST} ^www\.krs\.solar [NC]
    RewriteRule ^(.*)$ http://krs.solar/$1 [L,R=301]
    RewriteRule ^updates/(.*)$ updates.php?title=$1 [L]
    RewriteRule ^([^\.]+)$ $1.php [NC,L]
