You don't have to touch any code to install smart survey. Just follow the simple step
Step 1:(Requirements) HTTP Server. For example: Apache. mod_rewrite is required, but by no means required. PHP 5.3.0 or greater (We have used CakePHP version 2.6). Make sure /lib, /app/tmp and app/Config directory permission is 777. It means, this directory is writable.
Step 2:(File upload) Extract zip file to your desired places. For example public_html/survey
Step 3:(Database creation) Create a database and obtain user/pass from your hosting panel
Step 4:(Install) Navigate url by browser, Like as http://example.com/survey
Fill up it with database credentials and press install button. Your default user/pass is email@example.com/123456. After successfully installed, change user/pass for yourself
