Overview of the issue
Using version of WordPress lower than 5.9.0 with WPML 4.6.9 can result in a fatal error:
Uncaught Error: Call to undefined function WPMLBlockEditor::wp_enqueue_block_style() in /wp-content/plugins/sitepress-multilingual-cms/classes/block-editor/Loader.php:97
Workaround
You can downgrade to WPML 4.6.8, try the beta version of WPML V4.6.10, or use the directions below to patch the code until a permanent fix is issued. Please make sure you have a full backup of your site before you modify any code.
Go to: wp-content/plugins/sitepress-multilingual-cms/classes/block-editor/Loader.php and look for the method \WPML\BlockEditor\Loader::maybeEnqueueNavigationBlockStyles replace it with:
public function maybeEnqueueNavigationBlockStyles() {
global $wp_version;
if ( version_compare($wp_version, '5.9.0' ) >= 0) {
if ( ! wp_style_is( 'wp-block-navigation', 'enqueued' ) || ! wp_style_is( 'wp-block-navigation', 'queue' ) ) {
wp_enqueue_block_style( LanguageSwitcher::BLOCK_LANGUAGE_SWITCHER, [
'handle' => 'wp-block-navigation'
] );
}
}
}
