How to solve this please help

Answer 1

I think this problem occurs due to permissions for the folders. Try to give 777 permissions to the "var" folder or else create a temp folder with a 777 permissions at your var folder.

Firstly, copy “/lib/Zend/Cache/Backend/File.php” to “/app/code/local/Zend/Cache/Backend/File.php”.

NOTE: If local folder is not available, create it..

Then in the file which you have created recently and in that,

on line 91 or near this line, you will find:

    'cache_dir' => null,
    Change to:
    'cache_dir' => "var/tmp/",
