How to configure custom error pages for all domains on Plesk server?

Question

How to configure custom error pages for all domains on the server?

Answer

1. Download linux_default_skeleton.zip from the How to change the default content for newly created domains in Plesk? article.
   Unpack it and modify the content of error_docs directory in a desired way.

2. Compress it back into a .zip archive. Please note that .zip archive should contain all the files and directories in its root (cgi-bin, error_docs, httpdocs and so on).

3. Upload this modified archive in Tools & Settings > Virtual Host Template menu, by selecting a file and pressing Send file button.

4. Enable Custom error documents option for domains/subscriptions using one of the following ways:

• For multiple subscriptions on a specific service plan: Enable option Custom error documents option in Service Plans > Example-plan-name > Hosting Parameters and then synchronize plan with subscriptions.

• For all domains at once via CLI:

1. Connect to the server via SSH

2. Run the following command:

   # for i in plesk bin domain --list; do plesk bin domain -u $i -err_docs true; done

Note: Some websites/applications might use their own custom error pages (by means of rewrite rules), so the changes might not be reflected on some domains.
