Cause

The domain mentioned in the error messages has been deleted, but PSA database still contains an entry for this domain.

Plesk database was not properly upgraded. The ' psa.DomainServices ' table has no records of the "web" type.

Resolution

Note: This solution involves editing of MySQL database using MySQL queries.

Note: Please check that the domain physically exists before making changes. If it does, back up all the domain content from the corresponding directories /var/www/vhosts/<domain> and /var/qmail/mailnames/<domain> (in case of Linux) or from C:\Inetpub\vhosts and %plesk_dir\MailEnable\postoffices% (in case of Windows).

There are several possible scenarios:

Scenario 1. Domain physically exists in Plesk

1. Connect to the server over RDP (Plesk for Windows) or SSH (Plesk for Linux).

2. Create backups of the Plesk databases.

3. Access Plesk database. Run the following command in "cmd.exe command interpreter" (Plesk for Windows) or via "SSH command line" (Plesk for Linux):

   # plesk db

4. Remove the domain mentioned in the error  from the PSA database and recreate it from scratch, for example:

   mysql> DELETE FROM domains WHERE id='41';
   Query OK, 1 row affected (0.04 sec)

5. Ensure that there are no orphaned records in the databases by the following way (click to expand)

   • create databases backups (click to exapand):

     MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump --skip-extended-insert --complete-insert -u admin psa > /root/psa`date +%F_%H-%M`.sql
     
     MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysqldump --skip-extended-insert --complete-insert -u admin apsc > /root/apsc`date +%F_%H-%M`.sql
     
     ls -lt /root/ | head -n3
     total 31112
     -rw-r--r-- 1 root root 224955 Nov 23 22:45 apsc2015-11-23_22-45.sql
     -rw-r--r-- 1 root root 14023153 Nov 23 22:44 psa2015-11-23_22-44.sql

   • search for the values mentioned in the error messages, for example:

     grep 'bd314c87-865a-46e6-b694-342e71899445' /root/apsc2015-11-23_22-45.sql
     grep 'bd314c87-865a-46e6-b694-342e71899445' /root/psa2015-11-23_22-44.sql
     grep 'example' /root/apsc2015-11-23_22-45.sql
     
     grep 'example' /root/psa2015-11-23_22-44.sql | grep -v -E 'log_components|exp_event'
     INSERT INTO `Configurations` (`id`, `name`, `serviceNodeId`, `file`, `version`, `objectType`, `objectId`, `status`, `active`, `description`, `errorFile`) VALUES (115,'nginxDomainWebmail',1,'/etc/nginx/plesk.conf.d/webmails/example.com_webmail.conf','14240541100.61180300','nginxDomain',28,'ok','true',NULL,'');
     INSERT INTO `Configurations` (`id`, `name`, `serviceNodeId`, `file`, `version`, `objectType`, `objectId`, `status`, `active`, `description`, `errorFile`) VALUES (117,'nginxDomainVhost',1,'/var/www/vhosts/system/example.com/conf/nginx.conf','14307435570.48796000','nginxDomain',28,'ok','true',NULL,'');
     INSERT INTO `Configurations` (`id`, `name`, `serviceNodeId`, `file`, `version`, `objectType`, `objectId`, `status`, `active`, `description`, `errorFile`) VALUES (896,'domainVhost',1,'/var/www/vhosts/system/example.com/conf/httpd.conf','14483138520.02185500','domain',270,'error','true','Template processing failed: file = /usr/local/psa/admin/conf/templates/default/domainVhost.php, error = Template_Exception: No data.\

6. Remove found orphaned records. For example:

   MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin psa -e "DELETE FROM Configurations WHERE id IN (115,117,896)"
   MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin psa -e "DELETE FROM dns_zone WHERE id=272"
   MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -u admin psa -e "DELETE FROM hosting WHERE dom_id=270"

Scenario 2. Domain does not physically exist

1. Connect to the server over RDP (Plesk for Windows) or SSH (Plesk for Linux).

2. Access Plesk database. Run the following command in "cmd.exe command interpreter" (Plesk for Windows) or via "SSH command line" (Plesk for Linux):

   plesk db

3. Change htype of incorrectly removed domain to none :

   mysql> update domains set htype='none' where id=41;

4. Domain will become visible in Plesk interface with "No hosting".

5. Remove the domain through Plesk interface.

Scenario 3. Applicable when domain exists or does not exists.

1. Connect to the server over RDP (Plesk for Windows) or SSH (Plesk for Linux).
2. Create backups of the Plesk databases.

3. Access Plesk database. Run the following command in "cmd.exe command interpreter" (Plesk for Windows) or via "SSH command line" (Plesk for Linux):

   plesk db

4. Add the missing entries to the PSA database with MySQL query:

   First, check that there is an entry in 'DomainServices' for this domain:

   mysql> select * from DomainServices where dom_id = 41;
   +-----+--------+------+--------+---------------+----------------+
   | id | dom_id | type | status | parameters_id | ipCollectionId |
   +-----+--------+------+--------+---------------+----------------+
   | 322 | 41 | mail | 16 | 585 | 322 |
   +-----+--------+------+--------+---------------+----------------+
   1 row in set (0.00 sec)

   Add a similar "web"-type entry, and add related records to 'IpAddressesCollections' (click to expand)

   mysql> begin;
   mysql> select @dom_id := <missing_domain_id>;
   mysql> select @ip := (select dr.val from dns_recs dr, domains d where d.id = @dom_id and dr.dns_zone_id = d.dns_zone_id and dr.type = 'A' and dr.host = concat(d.name,'.'));
   mysql> select @ip_id := (select id from IP_Addresses where ip_address = @ip);
   mysql> INSERT INTO IpCollections VALUES (NULL);
   mysql> SELECT @ip_collection_id := LAST_INSERT_ID();
   mysql> insert into IpAddressesCollections (ipCollectionId, ipAddressId) values (@ip_collection_id, @ip_id);
   mysql> insert into DomainServices (dom_id, type, status, parameters_id, ipCollectionId) values (@dom_id, 'web' , 0, 0, @ip_collection_id);
   mysql> commit;
