/core/fn.fs.php on line 421

I am getting this error in my back end now and again… I can't see anything specific that is not working, but it troubles me that something is failing and my data/sales may be effected.



Warning: dir(/var/www/vhosts/path to my site frontend template/var/cache/block_16) [function.dir]: failed to open dir: No such file or directory in /var/www/vhosts/path to my site frontend template/core/fn.fs.php on line 420

Fatal error: Call to a member function read() on a non-object in /var/www/vhosts/path to my site frontend template/core/fn.fs.php on line 421




any help would be great. I am running 2.1.2
