 * Hello,
 * I noticed an error (screenshot – [https://snipboard.io/Q5jz9H.jpg](https://snipboard.io/Q5jz9H.jpg))
   in my browser console and I would like it cleared as it’s a concern to me. It
   seems the error has to do with Autooptimize and LifterLMS plugin.
 * Browser console error:
    JQMIGRATE: Migrate is installed, version 3.3.2 DevTools
   failed to load SourceMap: Could not load content for [https://www.daisyparenting.com/wp-content/cache/autoptimize/maps/css/lifterlms.min.css.map](https://www.daisyparenting.com/wp-content/cache/autoptimize/maps/css/lifterlms.min.css.map):
   HTTP error: status code 410, net::ERR_HTTP_RESPONSE_CODE_FAILURE

 * -> jquery migrate; that’s just jquery migrate saying hello and is normal
 * -> sourcemap: sourcemaps are used for debugging-purposes but are not supported
   by AO. the good news: sourcemaps are only loaded when you have the browser console
   open to begin with this has no impact what-so-ever on your site. if ever you 
   would want to debug, you can load your site with `?ao_noptimize=1` appended to
   the URL and the sourcemap will load.
 * hope this clarifies,
    frank
