 * Hi,
 * Google page speed insights show me this . . .
 * 
   Missing source maps for large first-party JavaScript
 * The culprit is
 * siteground-optimizer-assets/siteground-optimizer-combined-js. . . . . . .js
 * I saw a post asking about this from over two years ago so I’m wondering how to
   fix this now please? Has Siteground updated the plugin to make the Source Map
   or is there another solution please?
 * Thank you

 * Hello [@simonbvynl](https://wordpress.org/support/users/simonbvynl/),
 * Javascript and CSS combining does not generate source maps (which are only used
   in the browser for debugging purposes or in testing environments).
 * However, the mentioned warning does not mean that the optimization is not working
   as expected.
 * Regards,
 * Vladimir
