Add to cart events. Adds to Cart with matched content IDs was ok and now is 0%. I checked with Facebook Pixel Helper extension and the add to cart event is showin with a warning. I can see the content_ids to be [null]. Please we need you to fix this! * Plugin Author [adespresso](https://wordpress.org/support/users/adespresso/) * (@adespresso) * [5 years, 2 months ago](https://wordpress.org/support/topic/invalid-addtocart-value-parameter/#post-14190367) * Hi, * what version of Pixel Caffeine and WooCommerce are you using? Are using some other third-party plugins or theme that customize WooCommerce in some way? * [djwilko12](https://wordpress.org/support/users/djwilko12/) * (@djwilko12) * [5 years, 2 months ago](https://wordpress.org/support/topic/invalid-addtocart-value-parameter/#post-14190399) * hello i saw many other users were reporting same thing. I think it was working ok with previous version as this issue happens with latest. We have your plugin on many sites, using last woocommerce and wordpress version and the previous one. All stopped working. please kindly check we need a solution.

The plugin was previously working fine. Now you can see many users reporting the same issue. I can give you admin access for you to test. Please provide me private channel for communication. We really need to find a solution for this.

Your website URL was very helpful and we discovered that the issue is when using the WooCommerce Side Cart plugin. That’s your case, I don’t know if it’s the same for the other, but we are thinking about a general fix to embrace as many cases as possible. * We hope to release the fix within the next few hours. - This reply was modified 5 years, 2 months ago by [adespresso](https://wordpress.org/support/users/adespresso/). * [djwilko12](https://wordpress.org/support/users/djwilko12/) * (@djwilko12) * [5 years, 2 months ago](https://wordpress.org/support/topic/invalid-addtocart-value-parameter/#post-14200880) * Thanks.
