Checking if the REST API is Being Blocked

In WordPress, a REST API (Representational State Transfer Application Programming Interface) is a set of rules and protocols that allows different software applications, including websites and mobile apps, to communicate with each other over the internet. It enables interaction between your WordPress website and other applications or services, allowing data to be retrieved, updated, or deleted remotely.

The WordPress REST API provides a standardized way for developers to access and manipulate various content and functionalities of a WordPress website, such as posts, pages, users, categories, and more. The REST API plays a crucial role in WordPress updates. If it’s blocked, updates won’t work as expected.

  •  Go to Tools > Site Health in your dashboard.
  • If there is any issue, it will display “The REST API encountered an unexpected result”.  How to Fix WordPress Updating Failed or Publishing Failed
  • If there isn’t any problem with REST API, you’ll see “The REST API is Available”How to Fix WordPress Updating Failed or Publishing Failed

Look for any issues related to the REST API. If flagged, follow the provided suggestions to address the problem.

Checking for Plugin Conflicts

Conflicts between plugins can disrupt updates. Identifying the problematic plugin can help you resolve the issue.

  1. Deactivate Plugins: Temporarily deactivate all plugins from the Plugins menu.
  2. Test Updates: Try updating or publishing content. If it works, reactivate plugins one by one to find the conflicting one.

Checking for Theme Conflicts

Themes can also cause issues during updates. By switching to a default WordPress theme, you can determine if the theme is causing the problem.

Switch Themes: Navigate to Appearance > Themes and activate a default theme like Twenty Twenty-One.

Test Updates: Try updating your content. If successful, your original theme might be the culprit.

Checking Website Firewall Service if Blocked

Firewall services can sometimes block WordPress functions necessary for updates. Ensure your firewall isn’t causing the problem.

Reach out to your hosting provider’s support for guidance on checking firewall settings.

Turn On and Examine the WordPress Debug Log

The debug log provides detailed error information. Enabling it can help diagnose the update issue.

Edit wp-config.php: Access your website’s files and locate the wp-config.php file. Go to your cpanel and then navigate to the file manager and locate the wp-config.php file inside the public HTML.

define( 'WP_DEBUG_LOG', true );

Switch to Classic WordPress Editor

If you’re encountering errors while using the block editor, switching to the Classic Editor might help.

Install Classic Editor: Go to Plugins > Add New and search for “Classic Editor.” Install and activate the plugin. define( 'WP_DEBUG', true ); define( 'WP_DEBUG_LOG', true ); define( 'WP_DEBUG_DISPLAY', true );

Set Classic Editor as Default: In the Writing Settings (Settings > Writing), select “Classic Editor” as your default editor.
