PHP 8.1.27 – Fatal Error

Tried several 8.x versions and Code-Snippet will always break it. Is there any fix for it?

Deactivating Code-Snippet will make the site work.

O.k. I was able to narrow it down. Creating a PHP Snippet do deactivate Gutenberg blocks will cause the fatal error:

<?php //Remove Gutenberg Block Library CSS from loading on the frontend function smartwp_remove_wp_block_library_css(){ wp_dequeue_style( 'wp-block-library' ); wp_dequeue_style( 'wp-block-library-theme' ); wp_dequeue_style( 'wc-blocks-style' ); // Remove WooCommerce block CSS } add_action( 'wp_enqueue_scripts', 'smartwp_remove_wp_block_library_css', 100 );

or similar one, will not work, too.

Any idea?

//Remove Gutenberg Block Library CSS from loading on the frontend
function smartwp_remove_wp_block_library_css(){
wp_dequeue_style( ‘wp-block-library’ );
wp_dequeue_style( ‘wp-block-library-theme’ );
}

add_action( ‘wp_enqueue_scripts’, ‘smartwp_remove_wp_block_library_css’ );if (condition) {

}

It’s not limited to this shortcode there are more than this code which throw errors …

I edited the snippets again and again. maybe 50 times. And somehow it runs, now. I do absolutely not know what caused this issue after updating to PHP 8.x

Maybe it was some kind of server cache? I don’t know. It does run again at the end …

This is entirely down to your snippet. You have a random if (condition) {} at the end for some reason.

I recommend taking some time to format the snippet code properly to avoid issues like this.

As I wrote I was able to fix it. But it was no problem for 1 year with PHP 7.4. And the other snipped did not have any wrong code at all.
