Weird, I was about to write I could not reproduce, but at the 5th test indeed the problem appeared. I reloaded the homepage 10 times in the browser (with an empty cache), but was not able to reproduce it there, so it looks like a fluke at Pagespeed’s side? What you could do -and it would further improve performance- is look into “remove render-blocking CSS”, adding “above the fold CSS” which will be inlined in the HTML and which will render the page until the full CSS-file loads? There’s more info in the AO FAQ, look for “inline & defer CSS”.
hope this helps,

any news on this anis1287 ?
Hi Frank,
Sorry i was caught up with work and forget to reply on this.
The issue is apparently with your plugin. I don’t have this when i let the css files uncombined, or when i tried W3 total cache css combine option.
Hope that helps.
and have you been able to reproduce the problem as a visitor to the site, i.e. in a browser instead of with pagespeed insights?
No that happen only with google pagespeed
Super-weird, afraid the only thing I can do is propose the “critical CSS” workaround (which also has performance advantages, yay) .. as (as far as I know) there’s no way to debug why Pagespeed Insight might occasionally not load the CSS.
Update on this.
After a theme update. The issue was gone. So it was apparently a compatiblity issue with the theme. Blocksy theme.
good to know wp-anis, have you reached out to blocksy developers about this (undoubtedly hard to troubleshoot) issue?
Yes of course.
They said it’s a server side issue.
