[Closed] toolset and critical error

Hi Itamar
alert message is still there in the living site

Hi, actually I have a severe issue that cannot let me login in. This seems to be created by WPML as well.
There was a snippet provide by WPML support to avoid htaccess to be rewrited

add_filter('mod_rewrite_rules', 'fix_rewritebase');
function fix_rewritebase($rules){
$home_root = parse_url(home_url());
if ( isset( $home_root['path'] ) ) {
$home_root = trailingslashit($home_root['path']);
} else {
$home_root = '/';
}

$wpml_root = parse_url(get_option('home'));
if ( isset( $wpml_root['path'] ) ) {
$wpml_root = trailingslashit($wpml_root['path']);
} else {
$wpml_root = '/';
}

$rules = str_replace("RewriteBase $home_root", "RewriteBase $wpml_root", $rules);
$rules = str_replace("RewriteRule . $home_root", "RewriteRule . $wpml_root", $rules);

return $rules;
}

It seems causing the issue now
Plugin corrente: WooCommerce Multilingual & Multicurrency (versione 5.3.7) Versione PHP 8.2.21 Dettagli dell'errore ==================== Un errore di E_ERROR è stato causato nella linea 232 del file /web/htdocs/www.pievedepitti.it/home/wp-content/plugins/woocommerce-multilingual/classes/class-woocommerce-wpml.php.

and that's what my web server support wrote me about that:
internal server error è dato dal plugin WPML che modifica all'interno del file .htaccess la direttiva da RewriteBase / a RewriteBase /en generando l'errore.

site is now on but htaccess issue still to be solved.
I kindly ask you to check the script and let me know eventually if the code is Ok or not.
I created a backup. User and password to log in are the same you used already
