I am working with Magento 1.7 and suddenly I have this error when I go to cache management:

cache_dir must be a directory

I tried this solution to change this file lib/Zend/Cache/Backend/File.php

'cache_dir' => 'null' to 'cache_dir' => 'tmp/' but does not work

  • what is you config in local.xml? do you have any specific settings for cache? – FlorinelChis Sep 11 '13 at 9:46
  • i don't use setting cache in local.xml – Amirov Sep 12 '13 at 10:59
  • Create /var/tmp folder and give 777 file permission. This will solve your issue. – Vinoth Oct 10 '15 at 7:07

Go to location lib/Zend/Cache/Backend/ and open file.php and change: null to NULL

See:

protected $_options = array(
    'cache_dir' => NULL,
    'file_locking' => true,
  • I thougt the cache_dir error was about /var/cache, but it seems about something else. Can you explain whats going on because this fixed my problem. – Akif Sep 11 '15 at 14:28

Make sure that your var and var/cache directories are writable.
The issue generally arises when var directory is not writable.

  • var and var/cache directories are writable (all privileges 777) – Amirov Sep 11 '13 at 12:25
  • Also Check permissions for media directory, if works then good or Try this - Go to location lib/Zend/Cache/Backend/ and open file.php and change 'cache_dir' => 'null', to 'cache_dir' => 'full path to magento root directory/tmp' – Anshu Mishra Sep 11 '13 at 12:47

  • I tried all solutions searched but i have the same problem – Amirov Sep 13 '13 at 13:47

from Magento CE1.4 the 'cache_dir' value should be NULL without the quotes.

Also make sure the var/cache directory exists and is writeable and try and create a writeable tmp dir in your root.

I think this post might be related to your issue

  • but i have this error when cache_dir=>null – Amirov Sep 11 '13 at 9:29
  • In your question the value is 'null', I've had this before with a upgrade where I had to change it to null. Also make sure that this file isn't overwritten in the local code dir :) – Sander Mangel Sep 11 '13 at 9:32
  • I re-edit my cache_dir=>'null' as default and i don't understand what file in the local dir ? – Amirov Sep 11 '13 at 9:42
  • Zend libraries can be overwritten from app/code/local/Zend/... – Sander Mangel Sep 11 '13 at 9:43
  • i don't have Zend libreries in app/code/local – Amirov Sep 11 '13 at 9:46

Finally I found a little strange solution. I just add a new directory magento/null (777) in magento and it's resolved my problem.

It's strange

  • In that case it was expecting the path to a directory as a string. I bet if you change it to 'var/cache' it'll work with the old caching directory. – Sander Mangel Sep 13 '13 at 14:43
  • yes it's true it's work with 'var/cache'. Why other solutions does not work with me? can you explain me? – Amirov Sep 13 '13 at 14:49
  • and you're sure it doesn't work if you change the value to null without quotes around it? – Sander Mangel Sep 13 '13 at 14:49
  • without cache_dir=>null doesn't work and with cache_dir=>'null' it's work when i add null directory in magento root – Amirov Sep 13 '13 at 14:53
  • Hm very strange, well good it works now – Sander Mangel Sep 13 '13 at 14:56

In my case multiple instances of Magento are running in different directories so absolute paths were required instead of relative paths in lib/Zend/Cache/Backend/File.php.

Relative: 'cache_dir' => 'var/tmp/'

Absolute: 'cache_dir' => '/var/www/domain.com/var/tmp/'

This is a sample server environment, yours will be different so don't copy that line.

var/tmp already existed and permissions didn't matter. The issue in my case is a configuration apparently from the installation. When running a diff from command line on the /downloader/ directory there are inconsistencies in the *.cfg files in the instances where the Magento Connect (/downloader/) would not display.

Open /lib/Zend/Cache/Backend/File.php. Line 99 'cache_dir' => 'var/tmp/'

So Magento is trying to refer /var/tmp/ folder and either it couldn't be able to read or write this folder.

So you got 2 solutions,

Solution 1: Give 777 file permission to /var/tmp/ folder.

Solution 2: Open /lib/Zend/Cache/Backend/File.php. Change line 99 to 'cache_dir' => 'null'

Hope this helps.

I just created a /tmp directory in my Magento 1.7 root, and gave it 777 permissions. Magento didn't have permission to create the /tmp directory itself.
