Optimize CSS setting breaks site

had a look at your website with & without AO (one can disable AO on a per-request basis by adding ?ao_noptimize=1 to the URL) and both look the same, so I don’t see anything breaking (you’re “inlining all CSS”)?

as for google pagespeed insights; great score, no blocking resources to be seen ??

The site linked above seems to load ok now. However, I also use autoptimize on a multi-domain website and here only the main domain, i.e. the URL of the WP installation, loads as intended with CSS optimization enabled. The other domains serving the exact same files don’t.

Main domain: https://getpopcorntime.org (loads fine with CSS optimization)

Mirror domain: https://getpopcorntime.co.uk (doesn’t load fine with CSS optimization)

that’s because .co.uk has css from both .org and .co.uk in it, AO by default only aggregates from the domain which the request was for (.co.uk). you could either try setting CDN-url to //getpopcorntime.org or use the API to tell AO that the .co.uk and the .org are actually the same.

I see, that makes good sense. I tried setting .org as the CDN-url but it doesn’t work so I’m left with the API solution. Can you tell me how to accomplish telling it that the two domains are the same?

ok, try something like this;

add_filter('autoptimize_filter_cssjs_multidomain','swahlgren_add_domains');
function swahlgren_add_domains() {
    return array("getpopcorntime.org", "getpopcorntime.co.uk");
}

it might also be worth it to upgrade to the in-development version of AO which has significant improvement in the logic to decide what can and what can’t be aggregated. these changes will eventually be in the next release (no ETA yet), but if you want you can download the development-version here and overwrite your wp-content/plugins/autoptimize folder with the contents of autoptimize-master in the zip-file.

Help a brother out; where do I add the filter? ??

Thanks for trying to help!

You can use the code snippets plugin or, if you know what you’re doing, add it to your child theme’s functions.php.

Upgraded to the development version and now it works!
