This command returns not empty output:
# /usr/local/psa/bin/extension -l
Orphaned extension record is present in database.
Create backup of
# mysqldump -uadmin -p`cat /etc/psa/.psa.shadow ` psa Modules > plesk_psa_backup_modules.sql
Remove records one-by-one from
Modulestable checking what record causes the issue.
When orphaned record is found, restore
Modulestable back and remove that orphaned record again:
# mysql -uadmin -p`cat /etc/psa/.psa.shadow ` psa < plesk_psa_backup_modules.sql
mysql> delete from Modules where id=1;
id 1 is the number of corrupted module in database.
