 * Hi,
    I am receiving these errors on my Facebook business manager. We haven’t 
   change any code in the code parameters. It was working properly before, till 
   yesterday that we received these messages:
 * > **1. Server Sending Invalid Match Key Parameters for AddToCart Event**
   >  Your
   > server is sending an invalid ip_address parameters value for your AddToCart
   > event. This may be because there was an error in the parameter value.
 * > **2. Server Sending Invalid Match Key Parameters for ViewCategory Event**
   >  
   > Your server is sending an invalid ct, st, zip parameters value for your ViewCategory
   > event. This may be because there was an error in the parameter value.
 * How can I fix it?

 * Hi [@mjmontero](https://wordpress.org/support/users/mjmontero/)
 * We’ve been in touch with Facebook about this error in the past, and this is what
   we’ve learned from their replies:
 * • this warning only occurs with server to server events (added in Facebook for
   WooCommerce v2.0)
    • it can be the result of a platform issue – which wouldn’t
   be fixable from within the plugin • Facebook will not share more specific event
   data with us for privacy reasons • there aren’t any events in the plugin’s logs
   with missing user_agents or ip_addresses
 * Facebook has assured us that they’re looking into providing more information 
   for this error in a future release, such as showing the affected URL and the 
   parameter and what is wrong with it. They did also mention, however, that even
   with some additional details, it would not likely be able to be resolved by the
   plugin, as it can be at the platform level.
 * They weren’t able to pass along an expected date for release, though they did
   mention that there are often feature updates added after the holidays.
 * It seems that at this moment, we’ll need to wait for this release before looking
   at the Invalid Match Key parameter further. Please do let us know if you hear
   something different directly from Facebook!

 * So, as I understand there is not immediate solution? We will need to wait for
   facebook release? We are concerned that our campaigns and selling are being affected
   by this. Our facebook adds and store are affected.
 * How do I know about this release, if its not from the plugin?

 * Hi [@mjmontero](https://wordpress.org/support/users/mjmontero/). I’m sorry that
   we don’t have any further information at this time. As you noted, the update 
   would be coming from Facebook and would not reflect in the plugin. You would 
   notice any changes in the messaging in the Facebook Business Manager.

 * Having the same issue,
 * The advanced matching value for [ct] is missing, or is formatted incorrectly.
 * The plugin is working fine in 2 another domains.
 * Once you have any update we will appreciate guys.
 * Thanks.

 * Continue having issues with these parameters I mentioned before. I have been 
   investing lots of time to figure out want can be happening. I did notice some
   errors directly in the Facebook for Woocommmerce that I think can be affecting
   the Pixel data.
 * By some reason in some products of the store the parameters are not been pass
   correctly, for example I have a machine that has 3 options because of its colors.
   When the data is passed to Facebook store a fourth option is added with a 0 in
   the price, creating problems in the gathering of data.
 * Another example is the product if passed but without price, all of them appear
   at 0, and by consequence they are not shown in facebook catalog. This creates
   when the user clicks “Add to cart” button to give an error message
 * > The Facebook pixel activated 2 times on this web page, which can cause errors
   > in your event tracking
 * What can I do? I already force push the transfer of data to see if the prices
   where pass correctly but nothing has helped.

 * Hi [@mjmontero](https://wordpress.org/support/users/mjmontero/)
 * This kind of problem can be caused by a conflict with your theme or with another
   plugin.
      The best way to determine this is to:
    - Temporarily switch your theme to [Storefront](https://www.woocommerce.com/storefront/)
    - Disable all plugins except for WooCommerce and Facebook for WooCommerce
    - Repeat the action that is causing the problem
 * If you’re not seeing the same problem after completing the conflict test, then
   you know the problem was with the plugins and/or theme you deactivated. To figure
   out which plugin is causing the problem, reactivate your other plugins one by
   one, testing after each, until you find the one causing conflict. [You can find a more detailed explanation on how to do a conflict test here.](https://docs.woocommerce.com/document/how-to-test-for-conflicts/)

 * [@amandasjackson](https://wordpress.org/support/users/amandasjackson/) the issue
   I am having is with the passing of the information of the wordpress to the facebook
   store, even thought I change of theme and disable plugins I still have issues
   of how the data is passed. The issue is presented in products that have more 
   than one option to choose.. As I mentioned before this is creating duplication
   of data events.. and creating issues in my facebook adds.
