Please attempt to disable all plugins, and use one of the default (Twenty*) themes. If the problem goes away, enable them one by one to identify the source of your troubles. * [cherdt](https://wordpress.org/support/users/cherdt/) * (@cherdt) * [3 years, 9 months ago](https://wordpress.org/support/topic/wordpress-version-6-update/#post-15933316) * [@stephyf](https://wordpress.org/support/users/stephyf/) I found that there were a number of changes to `wp-settings.php` in the WP 6.0 upgrade, including the following new line: * `require ABSPATH . WPINC . '/block-supports/utils.php';` * That file contains the definition for the `wp_should_skip_block_supports_serialization()` function. Adding that line fixed my problems. * Normally I don’t update `wp-settings.php` during an upgrade, but you may find it worthwhile to compare the differences. * [stewa75](https://wordpress.org/support/users/stewa75/) * (@stewa75) * [3 years, 9 months ago](https://wordpress.org/support/topic/wordpress-version-6-update/#post-15967975) * [@cherdt](https://wordpress.org/support/users/cherdt/) you saved me, thank you very much Viewing 12 replies - 1 through 12 (of 12 total) The topic ‘WordPress version 6 update’ is closed to new replies. * In: [Fixing WordPress](https://wordpress.org/support/forum/how-to-and-troubleshooting/) * 12 replies * 4 participants * Last reply from: [stewa75](https://wordpress.org/support/users/stewa75/) * Last activity: [3 years, 9 months ago](https://wordpress.org/support/topic/wordpress-version-6-update/#post-15967975) * Status: not resolved ## Topics ### Topics with no replies ### Non-support topics ### Resolved topics ### Unresolved topics ### All topics
