 * In the process of optimizing my website and for some reason WP Joli is causing
   this error in the console.
   DevTools failed to load source map: Could not parse
   content for *****url****/style-index.css.map: Unexpected token ‘<‘, “<!DOCTYPE“…
   is not valid JSON.Any idea what is causing this and how I can fix this? As soon
   as I disable the plugin it goes away. I tried troubleshooting by disabling all
   other plugins and just enabling WP Joli, and still causing it.

 * Hi,
 * I’m not quite sure how the plugin is affecting the file you are referring to (
   style-index.css.map). There is no such file in the plugin.
 * It is going to be difficult to troubleshoot without seeing the actual page. Would
   you mind sharing the URL so I can check this directly ? (here or to [hello@wpjoli.com](https://wordpress.org/support/topic/devtools-failed-to-load-source-map-9/hello@wpjoli.com?output_format=md))

   this ?
