How to manage the compilation option?

The compilation is charged for compiling all files of Magento installation to create a single include path in order to increase performance. This tool should be disabled before the extension installation to avoid potential problems. You can temporary disable it in Backend » System » Tools » Compilation by clicking the Disable button and the Compiler include path will be disabled. Then, after the extension installation run the compilation process again.

 

IMPORTANT: please, make sure that you use the "Run Compilation Process" function after the installation, not the "Enable Compilation" - otherwise, you are likely to get backend fatal errors.
