 * Hello [@fixait](https://wordpress.org/support/users/fixait/),
 * Greetings for the day!
 * I have tride to check and replicate the same on my end but could see the warning
   message on category pages.
 * This could be due to some third-party plugin or theme conflict. Here’s what we
   can do to make sure:
 * Firstly, try to temporarily switch to another theme, like default themes like–
   Twenty-Twenty or Twenty Nineteen, and check if the error or issue persists.
 * Next, you can deactivate all the plugins temporarily variation swatches, and 
   WooCommerce and see if that solves the error. If it does then activate plugins
   one by one to see which plugin is causing the problem.

 * Hope this helps.
 * Let me know how it goes.
