 * My debug.log file is filled up with the following warning:
 * PHP Notice: Undefined variable: facebook_pixel_id in …/plugins/woo-product-feed-
   pro/woocommerce-sea.php on line 355
 * The warning is added 6-8 times per minute to the log file.
 * Thank you for letting me know how to fix that.

 * Thanks for using our plugin and reaching out to us. Sorry to hear you are seeing
   the PHP notice in your logs. It seems to be happening when you enabled the Facebook
   pixel feature but did not fill in pixel ID?
 * Anyhow, we have just pushed out a new release of our plugin that should fix the
   issue at hand. Can you try updating and see if the notices are gone?

   I am going to close this topic for housekeeping reasons now.
