[Support request] Site health issue: Page Cache not detected

[Kris]

Hi guys,

I ran the WP Site Health from the tools and it came back with the following performance issues:

1. Page cache not detected
2. You should use persistent object cache

I have your recommended Autoptimize installed, so I’m a bit confused about these error reports.

Could you please advice on these?

Thanks,

Hi Kris,

Can you check with your Hosting Provider if they offer Page Caching? It’s a common service provided by Hosting Providers.

If not, you can probably try replacing Autoptimize with WP Rocket for Page caching. See: https://docs.wp-rocket.me/article/1528-page-caching

Hi Fernando,
Thank you for your quick reply! I will check with hosting and get back to you if needed.
Did not find WP Rocket though in plug ins. Odd?
Thanks,
Kris

You’re welcome, Kris! Hope it goes well!

OK, they enabled page caching with the following good result:
“Median server response time was 78 milliseconds. This is less than the recommended 600 milliseconds threshold.”

LightHouse is still bad with FCP and LCP: https://i.postimg.cc/Z0kQ2WQD/image.png

I got this report from there:

“Resources are blocking the first paint of your page. Consider delivering critical JS/CSS inline and deferring all non-critical JS/styles. There are a number of WordPress plugins that can help you inline critical assets or defer less important resources. Beware that optimizations provided by these plugins may break features of your theme or plugins, so you will likely need to make code changes.”

Hi Kris,

Addressing FCP usually addresses LCP as well.

Checking your site this is the heaviest factor for both FCP and LCP: https://share.getcloudapp.com/bLuOPwYW

I would suggest using a CDN like Cloudflare so that your site’s resources are delivered faster. This article may be insightful: https://www.wpbeginner.com/showcase/best-wordpress-cdn-services/

The other issue is your server’s response time. This, most of the time has to do with your server speed.

As for other issues that your site may have, you can do a checklist with this article as a reference:

The arrow is pointing to Autoptimize in your image. Does that mean I should delete the plugin?

Also, I don’t know why it is reporting slow server response time as it is 78 milliseconds according to Site Health Status.

[Fernando]

Autoptimize is already serving the site’s resources in an optimized file. It’s not that big a size too at 42.8kb. It may be that the issue is the time it takes to load/get served on your site.

I would also highly recommend changing the file format of this image to next-gen: https://share.getcloudapp.com/6quN4Po9

Try uploading a webp image instead. Doing so could improve your FCP.
