How to upload Minecraft versions manually
Purpose
The purpose of this guide is to show you how to manually upload a server.jar of a specific version you want onto your server. *Some versions for various reasons aren't included on the built-in version selector.
*This is changing soon, we anticipate a new version selector release in due course which will further drive down the need for this.
Requirements
Your server must be stopped/off.
You have a general understanding of our Game Panel.
You understand you can use File Manager or SFTP.
Example
This example will guide you through installing Forge for Minecraft 1.20.1, specifically Forge version 47.3.12.
Procedure
1) Goto the Forge download page
2) In my case I'm going to the 1.20.1 download page - ttps://files.minecraftforge.net/net/minecraftforge/forge/index_1.20.1.html
3) Click on "Show All Versions"

4) Once you have found your version from the table click on 'Installer'

5) Follow the download page and skip any ads as needed
6) Your web browser should now download the forge installer .jar
7) If it does not, check your ad blockers or try another browser
8) Go to your Downloads folder and create a folder called "Forge"
9) Run the .jar from your Downloads folder
Note if the .jar does not run or open, you need to install Java on your system.
10) Click on "Install Server", click the three dots ' . . . ' and navigate to the "Forge" folder you just created inside the Downloads folder.


11) Now click 'OK'
12) Wait for the installer to complete and then click OK on the complete prompt

13) Check the /forge/ folder from the Downloads folder and you should see files in there now

14) Locate the 'libraries' folder, 'forge-1.20.1-47.3.12.jar' and 'minecraft_serer.1.20.1.jar'.
Missing the .jar files like the above screenshot? Follow 14.b) otherwise skip to 15)
14.b) If you cannot find your .jar files, you may need to locate them inside the libraries folder itself.

and

15) Now you will want to copy that libraries folder, the forge server .jar, the Minecraft server .jar
16) Paste these three items to your root Game Panel server directory by left-clicking and dragging the files to the File Manager

17) Now navigate to Configuration > Startup Parameters
18) We want to change Server Jar File parameter from (in my case) custom.jar to the name of the forge server .jar you copied.

change to

19) Start your server!
20) Are you getting an error that looks like this? "Error: Invalid or corrupt jarfile forge-1.20.1-47.3.12-server.jar"
20.a) You will need to go back to step 10) and click on Offline installer instead of Install server, repeat the other steps again and delete the corrupt .jar if you have it still on your server.
