警告：无法将空字符串分配给字符串偏移量wordPress 4.9.5

Question

Warning: Cannot assign an empty string to a string offset in /home/bofi9rpybgx8/public_html/stagging/hello/wp-includes/class.wp-scripts.php on line 426

Answer 1

I notice that problem in somewhere in the net try to replace in line 426

        foreach ( (array) $l10n as $key => $value ) {
        if ( !is_scalar($value) )
            continue;

        $l10n[$key] = html_entity_decode( (string) $value, ENT_QUOTES, 'UTF-8');
    }

With

        foreach ( (array) $l10n as $key => $value ) {
        if ( !is_scalar($value) )
            continue;

        if (!empty($value)) {
            $l10n[$key] = html_entity_decode( (string) $value, ENT_QUOTES, 'UTF-8');
        }
    }
