Magento 2.0.5. Could not determine temp directory, please specify a cache_dir manually

Question

After installing magento 2.0.5 on a webserver (allinkl.com) i am recieving following error when i try to add come products in the backend: "Could not determine temp directory, please specify a cache_dir manually"

i already looked for solutions, but without any sucess.

what i did till now:

1) changed file.php ('cache_dir'=> '/var/tmp/') 2) var/cache/ and var/tmp/ both have chmod777 recursively

also i contacted the webhost regarding this failure (in my case i can not edit php.ini), they told me to try following:

1) create "temp" folder in magento root 2) edit .htaccess: add "php_value session.save_path /www/htdocs/xxxx/domain/temp/"

But this also did not work out.

Would be great if somebody could tell me how to solve this issue.

Answer 1

try this:

navigate to file: vendor/magento/zendframework1/library/Zend/Cache/Backend.php

edit the file (line 211) replace:

if ($this->_isGoodTmpDir('/tmp')) {
    return '/tmp';
}

by this:

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

only add var before /tmp do not add slash (/) before var.

tested on the 2.0.7 and working.

hope this will help.
