Good day.
I upgraded to the latest WP, going to 6.1. Upgrade went great. I then noticed working on pages, posts, etc. and overall page speed insights scores - with regard to speed - degraded.

I am also seeing several warnings on the site health status page - pasted below. I use AutoOptimze and up until this upgrade - my scores have been amazing - and editing the site's content was really fast. Now I wish I could go back!

Site is

Unable to detect page cache due to possible loopback request problem. Please verify that the loopback request test is passing. Error: cURL error 61: Unrecognized content encoding type. libcurl understands deflate, gzip content encodings. (Code: http_request_failed)

Page cache enhances the speed and performance of your site by saving and serving static pages instead of calling for a page every time a user visits.

Page cache is detected by looking for an active page cache plugin as well as making three requests to the homepage and looking for one or more of the following HTTP client caching response headers:

cache-control, expires, age, last-modified, etag, x-cache-enabled, x-cache-disabled, x-srcache-store-status, x-srcache-fetch-status.

A persistent object cache makes your site’s database more efficient, resulting in faster load times because WordPress can retrieve your site’s content and settings much more quickly.

Your hosting provider can tell you if a persistent object cache can be enabled on your site.

@dondavidday Are you still having these issues? Have you upgraded to WP 6.2 yet?

Good morning!
The problem did go away. I have a set of notes I took to resolve it, but they are not here with me.
Thank you!
