Are you getting an update error or publishing failed error every time you update any post or page? Update failed error results when there is a communication failure with the WordPress REST API, a set of programming methods responsible for sending and receiving requests from the WordPress database. Our team can help troubleshoot updating failed errors in WordPress by implementing the following techniques:

Validating REST API status to identify the plugin or third-party app responsible for the issue

Modifying or deleting the .maintenance file

Ensuring correct file permissions to the root directory

Editing the wp-config.php file for manually updating FRP credentials
