API05003: WCPOS Plugin Outdated

What This Means​

The WCPOS plugin installed on your server is outdated and not compatible with your version of the POS application. You need to update the plugin.

Common Causes​

  • Plugin not updated — Auto-updates may be disabled
  • Update failed — A previous update attempt failed
  • Version mismatch — POS app updated but plugin wasn't
  • Staging/dev site — Testing on an older version

How to Fix​

1. Update the Plugin​

In WordPress Admin:

  1. Go to Plugins → Installed Plugins
  2. Find "WCPOS"
  3. If an update is available, click "Update Now"

2. Enable Auto-Updates​

To prevent future mismatches:

  1. Go to Plugins → Installed Plugins
  2. Find "WCPOS"
  3. Click "Enable auto-updates"

3. Manual Update​

If automatic update fails:

  1. Download the latest version from WordPress.org
  2. Deactivate the current plugin
  3. Delete the old plugin files
  4. Upload and activate the new version

4. Check for Update Errors​

If updates are failing:

  • Check file permissions on wp-content/plugins
  • Verify you have disk space
  • Look for PHP memory issues
  • Check error logs for details

5. Downgrade POS App (Temporary)​

If you can't update the plugin immediately:

  • Use an older version of the POS app
  • This is a temporary workaround only
  • Plan to update the plugin soon

Version Compatibility​

Always keep both components updated:

  • The POS application
  • The WCPOS WordPress plugin

Check release notes for any breaking changes when updating.
