Invalid css minification

Also completely unrelated, I was reading the source to locate the error, and there is an error in common.php

$purge_savvii = new \Savvii\CacheFlusherPlugin();
		if ( method_exists( $plugin, 'domainflush' ) ) {
			$purge_savvii->domainflush();
			return __( 'A cache purge request has been sent to <strong>Savvii</strong>', 'fast-velocity-minify' );
		}

$plugin in method_exists should be $purge_savvi

And on line 1022 there is an undefined variable $tvers
Line 1487 there is an undefined variable $cache_method

I have located the issue to the fvm_ensure_utf8 function

It’s an issue with php8.1+ only

Maybe we can remove UTF-7 from the mb_list_encodings() as a workaround

Like this:
$enc = mb_detect_encoding($str, array_filter(mb_list_encodings(), function($enc) { return strpos($enc, "UTF-7") !== 0; }), true);

Tested that it fixes the issue

I think I’m experiencing the same issues. On the front end font awesome icons are rendered as strange symbols. If I disable the plug in or “Disable CSS Files Minification?[ Will disable CSS Files minification for compatibility purposes ]” the icons render properly. I also running on php 8.1. Can you give me a little more context on what file and line to make the mb_detect_encoding change?

I can confirm moving back to php version 8.0.12. Eliminates the issue. Not a good solution either.

Thank you very much for reporting, I will get them sorted asap for the next update.

please check 3.3.9, thanks

Working great on 3.3.9 with php 8.1.0. Thanks for the fix and quick turn around… Great plug in!

Seems to be “back” in version Version 3.4.0 with php 8.1.17. Checking “disable CSS Files minification for compatibility purposes” and clearing caches gets this working again.
