solution:

  • open “errors” folder(E:\xampp\htdocs\magento\errors).
  • Change local.xml.sample to local.xml
  • Open E:\xampp\htdocs\magento\lib\Zend\Cache\Backend\File.php

protected $_options = array(
‘cache_dir’ => ‘null’,

change to

protected $_options = array(
‘cache_dir’ => ‘tmp/’,

  • Now the final step is to go create a “tmp” folder in the root Magento folder(E:\xampp\htdocs\magento)

I used my local computer path. You have to use according to local server.
