[Plugin: WP FullPage] CSS files not loading

I’ve migrated wordpress page manually to different hosting with copying database and files from FTP. I have no access to do it different way.
Page is working but it creates links to plug-in files dynamiccaly, and the css don’t work, because of different path.
When I’m checking homepage source file through my web browser I can see that links are different:
<script type=’text/javascript’ src=’http://rebelartistry.home.pl/globald_pl/wp-content/plugins/wp-fullpage/inc/__DIR__/assets//js/jquery.slimscroll.min.js?ver=1.0′></script&gt;
and there shouldn’t be “__DIR__” but “fullpage”.

Should I edit this dynamically created calls somewhere?
