My website http://www.bluebirdarts.pk has slowed down since I have updated my theme to the latest version. I am using WPRocket as the plugin right now for optimisation. The plugin is also crashing with this error since the theme has been updated:
I have 2 questions:
1. Is WpRocket the best plugin to use with Xstore theme? or is there some other?
2. GTMetrix recommended to use WPRocket. Is it even required or not?
