Style Issues

Hi

I recently installed this plugin in my website and it improved my performance, however, my website lost almost all the style. So in order to get it back I had to delete the plugin and re-upload 1 css file and 1 php file.
So my question is, how can I configure this plugin so my website doesn’t loose the style?

Thanks
