Support » Plugin: WooCommerce » WooCommerce / WP Facebook Pixel Incompatible Fatal Error

  • Resolved sondrakinsey


    I have been using WooCommerce and WP Facebook Pixel plugins together for at least six months without difficulties. However, on 06 April 2017 after upgrading WooCommerce to 3.0.0, I got the error following message on all pages on my site:

    Fatal error: Uncaught exception ‘Exception’ with message ‘Invalid product.’ in /home/content/p3pnexwpnas06_data02/89/2984289/html/wp-content/plugins/woocommerce/includes/data-stores/class-wc-product-data-store-cpt.php:133 Stack trace: #0 /home/content/p3pnexwpnas06_data02/89/2984289/html/wp-content/plugins/woocommerce/includes/class-wc-data-store.php(143): WC_Product_Data_Store_CPT->read(Object(WC_Product)) #1 /home/content/p3pnexwpnas06_data02/89/2984289/html/wp-content/plugins/woocommerce/includes/abstracts/abstract-wc-product.php(126): WC_Data_Store->read(Object(WC_Product)) #2 /home/content/p3pnexwpnas06_data02/89/2984289/html/wp-content/plugins/wp-facebook-pixel/assets/NSAFaceBookPixel.php(191): WC_Product->__construct(2) #3 [internal function]: NSAFaceBookPixel->get_WooCommerce_Events(Array) #4 /home/content/p3pnexwpnas06_data02/89/2984289/html/wp-includes/class-wp-hook.php(298): call_user_func_array(Array, Array) #5 /home/content/p3pnexwpnas06_data02/89/2984289/html/wp-includes/plugin.php(203): WP_Hook->apply_filte in /home/content/p3pnexwpnas06_data02/89/2984289/html/wp-content/plugins/woocommerce/includes/data-stores/class-wc-product-data-store-cpt.php on line 133

    The problem is resolved by deactivating either WooCommerce or WP Facebook Pixel 4.3.

    I welcome solutions which would enable me to re-enable WP Facebook Pixel, or recommendations on another WooCommerce-compatible plugin with the same functionality.

    It looks like it’s trying to get a product which is not a real product, which is why you get an exception. Notified the author?

    Uploaded version 4.4 which corrects this issue along with a few other minor bugs.

    Hi, I am having a similar problem but I don’t use that pixel plugin. My question is how did you figure out your problem was with your pixel plugin?

    I noticed “NSAFaceBookPixel” in the callstack/error message, so that was my original tip. I then deactivated the WP Facebook Pixel plugin, which resolved the issue. Then, to ensure it was a compatibility issue and not a bug in WP Facebook Pixel, I reactivated WP Facebook Pixel and deactivated WooCommerce, which also resolved the issue. Then, I knew it was a compatibility issue between the two plugins rather than a bug in either one alone.
