    I have used the basic tutorial shown here,Installing Minecraft Forge Server | HostHorde Forums, however the server refuses to start. The console shows this error:

    I got this from the support team seems to have worked for me to use java 8
    1. Rename your server's current JAR file to "custom_server.jar".
    2. Download https://www.hosthorde.com/downloads/8Launcher.jar
    3. Upload the file to your servers "jar" folder.
    4. In the Multicraft panel, set the JAR File to "8Launcher.jar".
    5. Reboot your server.
