Symptoms

It is not possible to access Horde webmail or open specific menus in webmail with one of the following error messages:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'horde.horde_prefs' doesn't exist

Server error when querying database.

A fatal error has occurred Could not instantiate PDO. PDOException: SQLSTATE[HY000] [1049] Unknown database 'horde'
In Plesk, it is not possible to remove/rename an email account or rename a domain with the error message:

DB query failed: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'horde.TABLE_NAME' doesn't exist, query was:

Cause

The database of Horde webmail is missing or corrupted.

Resolution

Note: If Horde webmail is not required on the server and another webmail is being used server-wide (Roundcube/MailEnable), remove the Horde component from the server.

For Plesk on Linux

Connect to the Plesk server via SSH.
For security reasons, create a copy of the /var/lib/mysql/horde directory:

# cp -r /var/lib/mysql/horde /root/
Empty the /var/lib/mysql/horde directory:

# rm -rf /var/lib/mysql/horde
Drop the 'horde' database:

# plesk db "drop database horde"
- If you get the message below, ignore it and move to step 4:
  
  CONFIG_TEXT: ERROR 1008 (HY000) at line 1: Can't drop database 'horde'; database doesn't exist
Switch to the directory with daily dumps:

# cd /var/lib/psa/dumps
Find the most recent dump that contains the 'horde' database:

# zgrep "Current Database:" mysql.daily* | grep horde
mysql.daily.dump.0.gz:-- Current Database: `horde`
mysql.daily.dump.1.gz:-- Current Database: `horde`
mysql.daily.dump.2.gz:-- Current Database: `horde`
- where mysql.daily.dump.0.gz is the most recent daily dump.
Restore the 'horde' database from the most recent daily dump. In this example, the 'horde' database is restored from mysql.daily.dump.0.gz:

# zcat mysql.daily.dump.0.gz | sed -n '/-- Current Database: `horde`/,/-- Current Database:*/p' | MYSQL_PWD=`cat /etc/psa/.psa.shadow` mysql -uadmin

For Plesk on Windows Server

Connect to the Plesk server via RDP.
Start a command prompt as an Administrator.
Switch to the directory with daily dumps:

C:> cd %plesk_dir%MysqlBackup
List all available Plesk daily dumps sorted by date (newest first):

C:> dir /O:-D

Directory of C:Program Files (x86)PleskMySQLBackup

Restore the Horde database:

C:> "%plesk_dir%Mysqlbinmysql.exe" -uadmin -P3306 -p horde < horde-20181018020721.sql

Note: MySQL admin user password is required for this operation. If the password is unknown, go to Tools & Settings > Database Servers > click next to MySQL/MariaDB to enter phpMyAdmin. In phpMyAdmin, click horde > Import > Browse to select the horde-....sql file from step 4 > then click Go to import the database.
