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.
<br />
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<br />
<br />
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<br />
```<br />
<br />
any help would be great. I am running 2.1.2
