  CONFIG_TEXT: statistics_collector[3644]: Relinking of virtual host logs `/usr/local/psa/admin/sbin/relink-vhost-logs --domain-name example.com --sys-user-login user' failed with code 3.#012Stdout:#012Stderr:'./example.com/logs' doesn't exist. Specify --create to create.#012ERROR: Cannot relink logs. Target directory '/var/www/vhosts/example.com/logs' is in invalid state.#012

Cause

The directory /var/www/vhosts/example.com/logs/ does not exist or has incorrect permissions and ownership.

Resolution

1. Login to the server over SSH.
2. Create the missing directory using the command from the error message with --create and --force options added, replace jdoe with system user's name and example.com with actual domain's name:

   # plesk sbin relink-vhost-logs --domain-name example.com --sys-user-login jdoe --force --create

3. Check the directory. It should have the following permissions/ownership:

   # ls -ld /var/www/vhosts/example.com/logs/
   drwx------ 4 jdoe root 4096 Sep 6 10:43 /var/www/vhosts/example.com/logs/
