Theme Optimization
These options allow you merging CSS and JS files into single files to have a better theme performance.
Once the option is enabled the merged file is generated automatically. You can remove all generated files using “Remove All Files” button. The system will delete all those files. Please do not worry, that does not remove the theme files.
Note that there can be a conflict with some 3rd party plugins. In this case, please disable either the optimization option or installed 3rd party plugin.
