 * Hi.
 * I’m writing to report an issue we’re seeing on the site while using your plugin.
   The server error log is showing the following warning:
 *     ```wp-block-code
       [24-Nov-2025 18:03:43 UTC] PHP Warning:  Undefined array key 206 in /wp-content/plugins/collapsing-categories/collapscatlist.php on line 222
       ```
   
 * Could you please check this and let us know how to resolve it, or if an update
   to the plugin is required?
 * I look forward to your feedback.
 * Regards,
   Marian
