 * I’m having an issue “setting up fake worker failed error” message on several 
   web pages.
    I’ve checked the support docs and do not see a place within the WP
   Optimize plugin settings to disable “aggregate JS files”. Can you please assist
   me in how to go about fixing this?  Thanks in advance,

   to see the link]_

 * Hi there,
 * To disable “aggregate JS files”, disable the option “Enable merging of JavaScript
   files” in WP-Optimize > Minify > JavaScript.
 * BUT this is unlikely to fix the issue. Instead, try adding `pdfjs-dist` to the
   setting “Exclude JavaScript from processing” (The issue is with the plugin that
   embeds PDFs).
