The update completes successfully, and the error is only visible if `WP_DEBUG_DISPLAY` is enabled on your site. * Unfortunately, there isn’t anything we can do at the moment to prevent this error from occurring. * This is a known and reproducible issue that affects any plugin that bundles ** Action Scheduler** and is updated via **WP-CLI** instead of through the WordPress admin dashboard. It’s not specific to The Events Calendar—plugins such as **WooCommerce**,** WPForms**, and others that vendor Action Scheduler are also affected. * The upstream Action Scheduler maintainers have classified this as an enhancement rather than a critical bug because the fatal error occurs during the **shutdown phase**, at the very end of the update process, after the plugin has already been updated successfully. As a result, the error is cosmetic and does not impact the actual update or the plugin’s functionality. * I hope this helps clarify what you’re seeing. Please let me know if you have any other questions or concerns. * Plugin Support [Darian](https://wordpress.org/support/users/d0153/) * (@d0153) * [1 week ago](https://wordpress.org/support/topic/error-updating-with-cli-to-current-version/#post-18951358) * Hi there, * It looks like we haven’t heard back from you in a while, so I’ll go ahead and close this thread for now. * If you still need assistance, feel free to reopen this thread or start a new one.
