I’ve already tried disconnecting and reconnecting a few times.

This is effectively a compatibility bug in their integration. Their code is trying to call: * ```wp-block-code contacts/v1/lists ``` * when HubSpot now expects the v3 Lists API. - This reply was modified 1 week, 4 days ago by [ksenter4](https://wordpress.org/support/users/ksenter4/). * Plugin Support [Saurabh – WPMU DEV Support](https://wordpress.org/support/users/wpmudev-support7/) * (@wpmudev-support7) * [1 week, 3 days ago](https://wordpress.org/support/topic/hubspot-integration-issue/#post-19003315) * Hello [@ksenter4](https://wordpress.org/support/users/ksenter4/), * Hope you’re doing well today! Thank you for sharing further information and the screenshot from the console. * Since the issue isn’t replicated on our lab environment, it probably doesn’t appear to be a general bug within the plugin itself. However, it could be something specific to your environment/set up. * Could you please confirm if you are using the most recent version of the Forminator plugin? Which is v1.57.1. If not, could you please update the plugin to the latest version and check if the issue still appears? * Also, since the console error points to HTTP 500 error on the AJAX request, can you please enable debug logging on your website after securing a full backup. Once done, please try opening the HubSpot integration and replicate the issue. * This will generate a log about the error on /wp-content/debug.log file. Could you please share the Fatal Error and the stack trace recorded there? This would help us check the issue further in the correct direction. * To enable debug logging, you can refer to the Guide here: [https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/#example-wp-config-php-for-debugging](https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/#example-wp-config-php-for-debugging) * You can also reach out to your hosting support if they can share the PHP Error Logs for the recent events. * Please share the logs with us so that we can take a closer look at them and check the issue further. * Kind Regards, Saurabh * Thread Starter [ksenter4](https://wordpress.org/support/users/ksenter4/) * (@ksenter4) * [1 week, 3 days ago](https://wordpress.org/support/topic/hubspot-integration-issue/#post-19003565) * Plugin wasnt up to date.
