invalid range in character class at offset 11

line 86（86行）
旧：
. ‘([\\w-_]+)’ // 2: Shortcode name
改为：
. ‘([\\w\-_]+)’ // 2: Shortcode name
w后面增加了\
因为PHP版本的提高，所有连字符’–‘（不作为范围字符使用）应该转义，’–‘从PHP 7.3将不再被视为范围字符。
（顺便87行w-也改为w\-）
修改完83-91行
private function getShortcodeRegexForId() {
return ‘\\[‘ // Opening bracket
. ‘(\\[?)’ // 1: Optional second opening bracket for escaping shortcodes: [[tag]]
. ‘([\\w\-_]+)’ // 2: Shortcode name
. ‘(?![\\w\-])’ // Not followed by word character or hyphen
. ‘(‘ // 3: Unroll the loop: Inside the opening shortcode tag
. ‘[^\\]\\/]*’ // Not a closing bracket or forward slash
. ‘(?:’ . ‘\\/(?!\\])’ // A forward slash not followed by a closing bracket
. ‘[^\\]\\/]*’ // Not a closing bracket or forward slash
