"Warning: include" error message

I have not done anything to my website in a few days then all of a sudden today it has started listing off a weird warning message at the top of all of my pages:

Warning: include(/hermes/bosweb/web208/b2081/nf.sumalifestyle/public_html/.sumabeachlifestyle.com/wp-content/plugins/wp-super-cache/wp-cache-base.php) [function.include]: failed to open stream: No such file or directory in /hermes/bosoraweb092/b2081/nf.sumalifestyle/public_html/.sumabeachlifestyle.com/wp-content/plugins/wp-super-cache/wp-cache.php on line 53

This is my website http://www.sumabeachlifestyle.com

Would really appreciate someone’s help to figure out how to fix. Thanks in advance!
