error "a:5:{i:0;s:71:Could not determine temp directory, please specify a cache_dir manually"

Question

I have moved my magento files from local server to live server. The site is running correctly and admin side login is working correctly. But when I click any menu links like "System->Configuration", it shows the below error in var/report/ error file.

a:5:{i:0;s:71:"Could not determine temp directory, please specify a cache_dir manually";i:1;s:3902:"#0 /httpdocs/includes/src/__default.php(61923): Zend_Cache::throwException('Could not deter...'

I have specified var/tmp folder manually in lib/Zend/Cache/Backend.php like

if ($this->_isGoodTmpDir('\\temp')) {
            return '\\temp';
        }
    else{
        return 'var/tmp/';
    }

and

I have specified var/tmp path in lib/Zend/Cache/Backend/File.php like

'cache_dir' => 'var/tmp/',

And folder permission of var folder is 777 and also created folder in root called 'tmp'. But Still I am facing the issue.

How can I fix this issue ? Any help appreciated.

Please open .htaccess file and put the line into it:

SetEnv TMP /your/magento/dir/var/session
