Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a va

    Hello,

    I am currently facing an issue on my website that I need assistance with. Whenever I try to process a payment using the Mercado Pago plugin as my payment gateway, I encounter the following error: “Uncaught TypeError: call_user_func_array(): Argument #1 ($callback) must be a valid callback, function ‘we_filter_checkout_posted_data’ not found or invalid function name.” This error seems to be originating from the ‘class-wp-hook.php’ file located in the ‘/home/foxcommtech/public_html/arg/wp-includes/’ directory.

    I am also using a custom checkout field plugin for field personalization. However, I suspect that the error is related to a missing or incorrectly named function called ‘we_filter_checkout_posted_data’, which should be defined either within my custom code or one of the plugins.

    I have already checked for updates for both the Mercado Pago plugin and the custom checkout field plugin to ensure they are up to date. I have also carefully reviewed my codebase, including recent changes, to verify that there are no typos or errors associated with the ‘we_filter_checkout_posted_data’ function.

    However, despite my efforts, I have been unable to resolve the issue. Therefore, I kindly request your assistance in resolving this matter. Could you please investigate the error message mentioned above and guide me on how to fix it?

    Thank you very much for your help. I appreciate your support in resolving this issue promptly.

    Best regards,
    Camila

    Hi @cc0905,

    Based on the error message, it does indeed seem that the function we_filter_checkout_posted_data is missing or incorrectly named. This function is likely to be part of your custom code or one of your plugins.

    I would recommend you to check your custom code again, particularly any recent changes you’ve made. If you had a backup of your site before the issue occurred, you might want to restore that and see if the error persists.

    Also, are you using the Checkout block or shortcode on your checkout page? If possible, could you try using the shortcode? Many themes and plugins don’t function properly with the checkout block, so switching to the shortcode might resolve the issue.

    If the issue still exists, try deactivating all your plugins except WooCommerce and Mercado Pago to see if the error still occurs. If the error disappears, reactivate your plugins one by one until the error reappears. This will help you identify if a plugin is causing the problem.

    If you have done all of this and the issue persists, it would be best to contact the developers of the Mercado Pago plugin and the custom checkout field plugin. They might be able to provide more specific help, as they are more familiar with the code of their products.

    Additionally, we recommend asking for insight related to those on either the WooCommerce Advanced Facebook group or the WooCommerce Community Slack. Many of our developers hang out there and will be able to offer insights into your question.

    Please note that we don’t provide support for third-party plugins or themes (please see our Support Policy).

    I wish I could help more, but hopefully, this gets you going in the right direction to get the job done.
