 * The word “DevTools” makes me wonder if there is some debug flag on.
 * The files are there with permissions 0644 in folders with permissions 0755.

 * Hi,
 * The browser only tries to load sourcemaps if the console is open. So these errors
   don’t have impact on the functionality of this plugin. However I will see if 
   I can add these sourcemaps if I have time.
 * BW,

 * Ah, no need to add. I have an issue on my site, and since this plugin is once
   those recently updated and throws those errors, I made the hasty conclusion that
   it might have to do with the issue. But since the erros manifest themselves when
   having the console open, this is clearly not the case.
