The Site Health tool in WordPress helps monitor your site’s performance and security. If you're seeing warnings such as "The REST API encountered an error" or "One or more plugins do not comply with the Consent API", don’t worry — we’ll walk you through simple ways to fix them.
“The REST API encountered an unexpected result” / “An error”
The REST API allows WordPress and plugins to communicate in the background. These errors usually happen due to:
a conflicting plugin or theme
security tools blocking access
caching misconfigurations
Steps
Login to hPanel
Login to Wordpress admin
Check your site URL in Settings > General
ℹ️ Note that your site URL should be your domain name (domain.tld)
4. Deactivate all plugins to find the cause of the error. If the website works, re-enable the plugins one by one. Otherwise proceed to next step;
5. Switch to a default theme.
“Your site could not complete a loopback request”
Loopback requests are used to run scheduled tasks and background processes which is commonly caused by maintenance mode or a broken plugin.
Steps
Deactivate plugins to check for conflicts.
Temporarily disable maintenance mode plugins.
“automatic_updater_disabled”
This means automatic updates are turned off, which may leave your site outdated.
How to fix:
Deactivate all plugins, then enable them one by one to find the cause.
Go to your wp-config.php file and remove this line:
define('AUTOMATIC_UPDATER_DISABLED', true);
If you’re unsure where your wp-config.php file is located at, please check the following article: Locating the wp-config.php file.
“Page cache is detected but the server response time is still slow”
This means you’re using a caching plugin, but your site is still slow.
Steps
Enable a CDN (like Cloudflare or Hostinger CDN) to reduce load time.
Optimize your site by following the steps here.
“Auto-loaded options may affect performance”
Autoloaded options are settings that load on every page. If there are too many, it slows your site down.
Steps
Use a database cleanup plugin to remove old data.
Optimize the database regularly.
“One or more plugins do not comply with the Consent API”
This means a plugin is setting cookies or running tracking scripts before the user gives consent, which may violate GDPR.
Steps
Update all your plugins — many add Consent API support over time.
Deactivate all plugins, then enable them one by one to find the cause and replace non-compliant plugins, or contact their developers.
