The error message you're encountering indicates an issue with the time zone configuration on your server, specifically related to the "Europe/Berlin" time zone.

Here are steps to troubleshoot and potentially resolve the issue:

1. Check Server Time Zone:

   • Log in to your server, and ensure that the server's time zone is correctly set to "Europe/Berlin." You can do this by running the following command:

     timedatectl

   • If the time zone is not set correctly, you can change it using the timedatectl command. For example, to set the time zone to "Europe/Berlin," you would use:

     Arduino

     sudo timedatectl set-timezone Europe/Berlin

2. Restart Services:

   • After changing the time zone, it's a good idea to restart any relevant services, such as the web server, to ensure that the changes take effect.

3. Check Web Presence Builder Settings:

   • In the Web Presence Builder, verify that the time zone is correctly set to "Europe/Berlin" within the application itself.

4. Clear Browser Cache:

   • Sometimes, cached data in your browser can cause issues. Clear your browser cache and try again.

5. Check for Software Updates:

   • Make sure that your server's operating system, Plesk, and Web Presence Builder are all up to date. Outdated software can sometimes lead to compatibility issues.

6. Review Logs:

   • Check the error logs on your server for any messages related to Web Presence Builder or time zone settings. This might provide more specific information about the issue.

7. Contact Support:

   • If the issue persists, consider reaching out to Plesk support for further assistance. They may have encountered similar issues and can provide specific guidance.

Remember to backup any critical data or configurations before making significant changes to your server or its settings.
