 * Hi there,
 * Been using Hummingbird for a few days and it’s mostly working now.
 * However I’ve spotted that some of its own files are now deemed “render-blocking”,
   especially CSS
 * hummingbird-assets/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.css
 * I can’t use your page/html caching tool for various reasons (conflicts with CDN
   and others), but I am using your compression.
 * What can I do to fix this issue please?
    Thanks!
 * FJ

 * Hi @martin-oxby
 * I hope you are doing well.
 * Sorry for the delay here, it seems we didn’t receive the notification about this
   question.
 * By default in the Automatic mode the plugin won’t modify the flow of CSS and 
   JS, so to remove the render blocking you can switch to manual mode and move the
   CSS and JS files to the footer following this guide: [https://wpmudev.com/docs/wpmu-dev-plugins/hummingbird/#asset-optimization](https://wpmudev.com/docs/wpmu-dev-plugins/hummingbird/#asset-optimization)
 * Now, the hummingbird-assets/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX.css is a combined
   version, you can click to open the reported file on the browser and on the top
   of the file you will find the real filename on the handle comment area.

 * Hello @martin-oxby ,
 * We haven’t heard from you for a while now, so it looks like you don’t have more
   questions for us.
 * Feel free to re-open this ticket if needed.
 * Kind regards

 * Sorry, I had meant to simply say “thank you” and “I’ll look into that then!”.
 * I never mean to open a ticket and ignore the reply, so apologies.
 * Thank you!
