Question: Apache is failing to start in Plesk: Error: New configuration files for the Apache web server were not created due to the errors in configuration templates: AH00112: Warning: DocumentRoot [/usr/share/plesk-service.localdomain] does not exist


Symptoms

• The following error message is displayed in Plesk:

Code Select Expand

Error: New configuration files for the Apache web server were not created due to the errors in configuration templates: AH00112: Warning: DocumentRoot [/usr/share/plesk-service.localdomain] does not exist AH00112: Warning: DocumentRoot [/usr/share/plesk-service.localdomain] does not exist AH00526: Syntax error on line 22 of /etc/apache2/plesk.conf.d/vhosts/example.com.conf: SuexecUserGroup configured, but suEXEC is disabled: Missing suexec binary /usr/lib/apache2/suexec.

Cause


plesk-web-hosting package is missing or was uninstalled accidentally during another package installation.
For example the unsupported vsftpd package was installed recently and it has removed several Plesk packages during its installation.


Resolution

1.Connect to the server via SSH

2.Remove the recently installed package, on this example vsftpd, Plesk uses ProFTPd instead:

Code Select Expand

# apt remove vsftpd
3.Navigate to Tools & Settings > Updates and press Add/Remove Components button.

4.Select required components for installation (for example, if plesk-roundcube was removed, select Webmail services/Roundcube for installation.

5.Press Continue button to install the packages. Missing plesk-web-hosting package will be installed automatically.

Web Application / How to Restore Snapshots

Last post by Suhitha - Sep 29, 2025, 02:44 AM

Question: How to Restore Snapshots

Recover your server to a previous state using a backup or snapshot.

Restoring a snapshot involves recovering the exact state of a system at the time the snapshot was created. Snapshots capture the complete configuration, including the operating system, applications, and data, making it easy to revert to a specific point in time. This process is essential for system recovery, testing, or duplicating environments, ensuring consistency and minimizing downtime.

Follow this guide to restore snapshots using the Vultr Customer Portal, API, CLI, or Terraform.

Note
When restoring a server backup that uses a static IP, you must reset the network to DHCP to obtain a functional IP address. If network configuration needs to be reset after restoring a snapshot, refer to Return a Vultr Server to the Default DHCP Configuration. Restoring a snapshot on existing Vultr Cloud Compute servers or provisioning new servers using snapshots may take an additional 10-15 minutes compared to standard operations.


Vultr Customer Portal

1.Navigate to Products and click Compute.

2.Click your target Vultr Cloud Compute instance to open its management page.

3.Navigate to the Snapshots tab.

4.Choose any snapshot you want to restore.
