Disabling/enabling a module is a popular operation for Magento store owners. Below, we will show you how to disable an extension correctly.
To disable any Amasty extension, please follow the next steps:
1. Edit app/etc/modules/Amasty_XXX.xml file (where XXX stands for the extension name/code).
2. Change "true" to "false".
3. Clear the cache.
Now you've completely disabled the module and it does not affect any Magento functionality.
Please, note that disabling module output under System>Configuration>Advanced does not deactivate the extension!
