Reporting an Issue with /cdn-cgi/challenge-platform/h/b/scripts/alpha/invisible.js" file on my website, pic-microcontroller.com

Dear Cloudflare Community,

I am writing to report an issue related to the use of the “/cdn-cgi/challenge-platform/h/b/scripts/alpha/invisible.js” file on my website, pic-microcontroller.com.

When I ran a performance test on my website using Google PageSpeed Insights, I received a warning related to the use of the deprecated StorageType.persistent property in the invisible.js file. They mention that “Please use standardized navigator.storage instead.”

The warning can be found under the “Best Practices” section of the report, and the link to the report is https://pagespeed.web.dev/analysis/https-pic-microcontroller-com/s1mzo513xz?form_factor=mobile.

I believe that this file is added by the Cloudflare plugin for WordPress, which integrates with my site to manage Cloudflare settings. Can you please advise me on how to resolve this issue?

Thank you for your attention to this matter.

Best regards,
Ayub Shakoor.

Hello Ayub!

You can simply ignore it. Don’t be crazy with PageSpeed Insights and other testing tools. You don’t need to achieve a 100 100 100… Score to have a great website and to make it fast for real people and seo bots.

cdn-cgi/challenge-platform/h/b/scripts/alpha/invisible.js

Is added by Cloudflare itself, not his plugin. This scripts help detects bots that try to access your website.
There’s a way to deactivate it: By disabling Bot Protections and Javascript Detection on your WAF.

But I don’t recommend will to do it. What’s better? Having a website more secure or having a 100 Score on automated tools? Put it in the balance. Even AMP pages get Google Speed Insights warnings, saying that their script is degrading performance but it’s not. And… It’s their script, so they should take care of it, not us.

Cheers!

Think: Is it really reasonable to make your site less secure just for a few extra points?
