 * This looks like an issue with the [Woo Variations Gallery](https://wordpress.org/plugins/woo-variation-gallery/)
   free plugin. You will need to bring up the issue on [their support forums](https://wordpress.org/support/plugin/woo-variation-gallery/).
   You also may have debugging enabled which you can disable in `wp-config.php`,
   see [WordPress Debugging](https://wordpress.org/support/article/debugging-in-wordpress/)
   and the WP_DEBUG & WP_DEBUG_LOG flags.
