cloned site breaks perhaps due to leftover files

Evening (noon) Heather ??

I doubt this is due to leftover files; if it works first and then after x hours/ days it doesn’t then this .. something else.

What I would suggest is;
* have AO active but WP Rocket off and wait a day or so (until it breaks)
* then re-enable WP Rocket with AO active but only with JS optimization and wait a day or so (or until it breaks)
* then have it with only CSS optimization and wait a day or so (or until it breaks)
* then have it with only HTML optimization and wait a day or so (or until it breaks)

And when things break:
* check if there are 404’s for some (AO’d) files
* check if there are JS errors on the browser console
* run a test at webpagetest.org to document what resources are (not) loaded

It seems like the issue is now resolved for the first website, but then a similar thing happened on another site: https://apartmentshoustonenergycorridor.com/

All of the background color and images disappear – all text is okay.

I noticed this error before I deactivated plugin:

U autoptimize_2bada2b336a2e433ca07ef9378bb2f02.js ncaught SyntaxError: Unexpected end of input
>

(and the word “Uncaught was broken up just like that)

…and then this after I deactivated plugin

window.Identity=window.Identity||[];function report(){var a=this.universal_zid.uuid;window.Identity.push(["cookify",a]);window.Identity.push(["pixel",window.location.href])}window.Identity.push(["fetch",report,function(){}]);id.push(RUID);

Do those mean anything to you? Or point to anything we can address?
This plugin has always worked seamless for us on many sites, together with WP Rocket. But I’ve found it necessary to use more features recently (such as defer JS, lazy load etc). All websites that used to be in the 90s for both mobile and desktop are all now in the red now on the new Lighthouse speed scoring. It’s been most challenging to get a good, stable mobile score.

In the meantime, I’m going to re-save my settings and see if it clears it like the other.

Afraid I’ll have to see it broken to make any sense of what is going wrong there Heather, but what you can always do is just disabling CSS or JS and seeing what of those is breaking things here.

And indeed; GPSI is a moving target and it has become a lot harder to get great scores.
