DISABLE YOUR SYSTEM CACHE
To prepare your Magento for production, you need to first disable system cache by going to the Administration Panel (http://yourhost.com/admin) and navigating to System --> Cache Management. Select the check boxes next to Layouts, Blocks HTML output and Translations and then under Actions select “‘Disable” and click Submit. Each of those Cache Types should have a red bar in the status area that reads ”DISABLED.” By doing this, it will help to ensure that you see a faithful reflection of your store front as you make the changes.
Note: Depending on what you are attempting to achieve, you may need to disable additional cache files in this area or even manually delete cache files in your folder structure. Do not manually delete folders unless you know what you are doing.
