 * I’m trying to update my cPanel/Wordpress PHP version from 7.2 to 7.4. When I 
   update to 7.4 I get a ton of error messages like this:
 * Warning: preg_match(): Compilation failed: invalid range in character class at
   offset 4 in /home/xxxxx/public_html/wp-content/plugins/lightbox-plus/classes/
   shd.class.php on line 1384
 * Warning: preg_match_all(): Compilation failed: invalid range in character class
   at offset 4 in /home/xxxxx/public_html/wp-content/plugins/lightbox-plus/classes/
   shd.class.php on line 700
 * Warning: preg_match_all(): Compilation failed: invalid range in character class
   at offset 4 in /home/xxxxx/public_html/wp-content/plugins/lightbox-plus/classes/
   shd.class.php on line 707

   fails. A problematic regexp.
