Could not determine temp directory, please specify a cache_dir manually problem in Magento

By Expertwebadvisor | Last Updated: August 17, 2015 | In: Magento

After moving a Magento store from one hosting to another, Magento admin shows exception: "Could not determine temp directory, please specify a cache_dir manually". This is usually due to the Shared web hosting but our hosting was not the Shared, Here in this post I am describing how to solve this problem either on the Shared or on the VPS, it is very easy and you can solve just by following the steps given below:

Could not determine temp directory, please specify a cache_dir manually problem in Magento

Step 1: Check the Folder permission for the cache directory, if it is not the 777 Please apply the 777 permission to the var/cache folder, Just by using the SSH
Command below:

sudo chmod 777 var/cache* -R

Step 2: Delete the Magento Cache Manually just by deleting the var/cache folder.

Step 3: Now Refresh the website and check the var/cache, Magento creates this folder again and check the permission of this newly created folder, if it is 777 then it is fine otherwise use the Step 1 and reset the permission to this folder. Hope it solve the problem, if the problem is still there:

Step 4: Navigate to the /lib/Zend/Cache/Backend/File.php and copy the File.php and create the folder app/code/local/Zend/Cache/Backend/File.php, as we know File.php is the Core Magento file and we suggest everytime not to change the Magento Core Files so that I have putted it into the app/code/local folder, now it will not affect the Magento Version Upgrade.

Step 5: Open the File.php and search for the ‘cache_dir’ => null, and change it ‘cache_dir’ => “var/tmp/”,

Step 6: Now refresh the browser cache and Magento cache as well, hope it solve the problem.
