Plugin and Themes

Plugin and Themes

Plugins and themes add functionality and presentation to WordPress, but they are also frequent sources of compatibility issues.

Fleet views

The Plugins and Themes views help you compare software across multiple instances.

Use them to review:

  • Installed versions
  • Active status
  • Available maintenance
  • Version differences
  • Compatibility or review signals

Instance plugin actions

Where your permissions and the plugin state allow it, plugin actions can include:

  • Search
  • Upload
  • Activate
  • Deactivate
  • Update
  • Delete

Instance theme actions

Theme actions can include:

  • Search
  • Inspect
  • Activate
  • Update
  • Delete

Understanding update availability

Do not assume that the absence of a detected update proves an extension is on its latest vendor version.

Premium, vendor-managed, private, custom, or otherwise non-public extensions may not expose the same update metadata as WordPress.org assets.

When CanaryWP cannot verify an update with sufficient evidence, the documentation and UI should treat the result as unknown or requiring review, rather than making an unsupported “up to date” claim.

Safe update workflow

  1. Confirm the target test instance.
  2. Create or verify a backup.
  3. Run a baseline.
  4. Update one component or a controlled group.
  5. Confirm the site still loads.
  6. Check WP Admin.
  7. Review logs.
  8. Run Site Testing.
  9. Review visual differences.
  10. Investigate failures before applying the same update elsewhere.

Activating and deactivating plugins

Activation state can change site behavior immediately.

After changing it, verify:

  • Public pages
  • WP Admin
  • Forms
  • Scheduled jobs
  • Integrations
  • Ecommerce functionality where applicable

Themes

Theme changes can produce functional as well as visual effects.

Do not validate a theme update solely by confirming that the homepage loads.

Review:

  • Header
  • Footer
  • Navigation
  • Templates
  • Responsive layouts
  • Forms
  • WooCommerce templates where applicable
  • Visual regression results

Deleting software

Deletion is destructive.

Confirm that the plugin or theme is not needed by the environment and that any relevant backup exists.
