AO and NGINX

no idea at all I’m afraid ps67481 … are your CSS-files on the same domain as your HTML and JS (by default AO doesn’t aggregate files that aren’t on the exact same domain)? do you have any errors in your PHP-errorlog?

If you want I could create a debug-version of autoptimizeStyles.php (and autoptimizeBase.php) to output extra stuff to your php errorlog.

ok, you can already use this one for autoptimizeBase.php. I’ll create an autoptimizeStyles.php-one later tonight or tomorrow morning.

and autoptimizeStyles.php with debug output is here; https://gist.github.com/futtta/a29935d8a9dab3421d6ab6af1ceb12aa

your logfile has

CSS read: extracting all CSS

but it does not have

CSS read extract found:

although that is the logical next step as from the code;

error_log("CSS read: extracting all CSS");
		if(preg_match_all('#(<style[^>]*>.*</style>)|(<link[^>]*stylesheet[^>]*>)#Usmi',$this->content,$matches)) {
			foreach($matches[0] as $tag) {
				error_log("CSS read extract found: ".$tag);

the regex if pure PHP (using PCRE under the hood) and a switch from Apache to NGINX can’t warrant this regression (also; there’s a considerable minority of other AO-users on NGINX that are not experiencing this issue).

careful conclusion; I suspect another type of conflict, possibly with another plugin. next step would be to selectively disable (and re-enable) plugins (and temporarily switch plugins) to identify the culprit?
