Cause

Entries from the hosting table were removed due to the Plesk upgrade failure.

Resolution

For Linux

Connect to the server via SSH
Create Plesk database backup.
Restore hosting table from pre-upgrade dump.

Note: the dump is located at /var/lib/psa/dumps/*preupgrade*.

# gunzip /var/lib/psa/dumps/mysql.preupgrade.<version and time stamp>.dump.gz
# sed -n -e '/DROP TABLE.*`hosting`/,/UNLOCK TABLES/p' /var/lib/psa/dumps/mysql.preupgrade.<version and time stamp>.dump > hosting.sql
# MYSQL_PWD=$(cat /etc/psa/.psa.shadow) mysql -u admin psa < hosting.sql

For Windows

Note: the dump is located in %plesk_dir%\\mysql\\backup or (in case if the database provider was different fom MySQL) at%plesk_dir%\\admin\\db\ folder.

Connect to the server via RDP
Create Plesk database backup.
On Windows the corresponding entries should be extracted manually using Notepad/Notepad++ utility and saved in a separate file, e.g. C:\\hosting.sql. Then use the saved file to restore the table:
- Open CMD and run the following command:
  
  C:\> plesk db < hosting.sql
