* I get a server error when updating/publishing posts, but only when I have ACFE
activated. I used ACFE to add taxonomies to posts when I built this site a few
years ago. WP core, themes, and plugins are all updated, still getting the same
issue. Error doesn’t occur when updating pages, but I’m not using ACFE on those.
Any ideas? I can shoot you a login.

* Hello,
* Thanks for the feedback!
* Well, it’s hard to tell without any error message. It could be a compatibility
issue with a third-party plugin too. I would recommend to enable the WP Debug
mode ([see documentation](https://developer.wordpress.org/advanced-administration/debug/debug-wordpress/)),
it will help you to identify the cause of the issue.
* To do so, you can add the following code in your `wp-config.php` file, right
before the comment: “That’s all, stop editing! Happy publishing”:
* ```wp-block-code
define('WP_DEBUG', true); // enable debugdefine('WP_DEBUG_LOG', true); // enable error logsdefine('WP_DEBUG_DISPLAY', false); // don't show errors on screen/* That's all, stop editing! Happy publishing. */
```
* This will log server errors in the file: `/wp-content/debug.log`.
* Once the debug mode code has been added, try to trigger the error again, and
open this file. You should see some error message. Please share it here.
* You can read more about how to debug [WordPress and ACF on our guide here](https://www.acf-extended.com/guides/debugging-wordpress-acf).
* Let me know if you found something!
* Thanks!
* Regards.

* Thanks for the follow-up. I’m not getting any errors logged with debug turned
on.
* Edit: Nevermind. Will followup shortly.

* Hello,
* The error message says your Taxonomy try to execute the function `update_attachment_publish_author()`
when a post is updated, but that function doesn’t exist (neither in WordPress
or ACF source code). This suggests you have some custom configuration in your
Taxonomy which point to this invalid function.
* Here is the WordPress source code that trigger the error (from `/wp-includes/
taxonomy.php:3567`):
* ```wp-block-code
if ( ! empty( $taxonomy->update_count_callback ) ) { call_user_func( $taxonomy->update_count_callback, $terms, $taxonomy );}
```
* If you registered your taxonomy with ACF Extended, I would recommend to head
over the “Tools > Taxonomies” admin menu, and check the “Update count callback”
setting on each taxonomy.
* By default, it should be empty. You’ll find more information about the `update_count_callback`
setting on the `register_taxonomy()` [documentation here](https://developer.wordpress.org/reference/functions/register_taxonomy/).
* I would also recommend to check your settings in your Taxonomies, see if you
have anything unusual.
* Thanks!
* Regards.
