Plesk WP Toolkit 5.9.2 and above does not detect instances that were detached

Symptoms

• When scanning instances in Plesk > WordPress > Scan the existing instance for example.com does not appear in the list.
• The instance for example.com has been detached from WP Toolkit recently.
• The WP Toolkit extension version is 5.9.2 and above.

Cause

Starting from WP Toolkit 5.9.2 detached WordPress instances are no longer re-added through the Scan procedure, making their detachment permanent.

Resolution

If the website should be added to WP Toolkit back for some reason, perform the following:

1. Log into Plesk.
2. Go to Domains > example.com > File Manager.
3. Find and remove the .wp-toolkit-ignore file in the domain's document root.
4. As soon as the file is removed, go to the WordPress menu and re-scan instances.
