Very effective

Thanks a lot for such an effective and efficient plugin. It will be great if its 『heaviness』 or 『robustness』 is simplified.

Deactivate and Delete

The simple solution to JetPack preventing access to your own WP site is to DEACTIVATE and DELETE Jetpack! Who on earth do those people think they are? Having a secure site and all setup with Godaddy and WP, should some IT tech’ees – apparently with a very high logic but absolutely no common sense – prevent me access to my own website? Just delete the crap and find another plugin …

About removing devicepx.css for my website

Thank you for reading my question

but I found that it is no use for my website, I could not figure out what wrong with this. Could you help me?

Note: I use Webpagetest after I add this code to my functions.php file, but It seems that my website still load file.

My website is:
