 * Hi,
 * After the recent plugin update to version 2.1, I constantly get the following
   error message:
 * WordPress database error: [Illegal argument to a regular expression.]
    SELECT
   wp_posts.ID FROM wp_posts INNER JOIN wp_postmeta ON ( wp_posts.ID = wp_postmeta.
   post_id ) WHERE 1=1 AND ( ( wp_postmeta.meta_key = ‘chart-categories’ AND wp_postmeta.
   meta_value RLIKE ‘[[:<:]]19[[:>:]]’ ) ) AND wp_posts.post_type = ‘size-chart’
   AND ((wp_posts.post_status = ‘publish’)) GROUP BY wp_posts.ID ORDER BY wp_posts.
   post_date DESC LIMIT 0, 1
 * I’m using PHP 7.3.5, and MySQL 8.0.16 in my environment. I would appreciate it
   if you could provide a solution to this problem, or fix it in the following updates.
 * Thanks in advance.
