• Domains were migrated from cPanel and the directories mentioned in the error above.

• Some of the directories migrated are broken symlinks.

Cause

Broken symlinks affect the Wordpress scan. This has been reported as bug ID PPPM-10965, which will be fixed in future updates.

Resolution

As a workaround remove the broken symlink:

1. Connect to the server via SSH.

2. Remove the broken symlinks in the error with the unlink command:

   # unlink example

3. Re-scan Wordpress instances in Subscriptions > example.com > Wordpress > Scan.
