How To Install Custom Builds/Versions of Forge and/or Custom Mods

Installing Forge through the 1-click Install list on your control panel

If the Forge version you need is an available option on our list then you do not need to install it manually.

We will always try and have the Recommended (and Latest builds if they are newer) for all Forge releases available - with the latest release version being updated once a week for new builds. If any of the available builds will work for the mods you are installing you can install them easily following these steps:

- Log into your account and go to your servers main page (Where the Start/Stop/Restart buttons are found).
- Change the drop down list of server options (Will be set to 'Default' if you have never changed this) to the Forge build you wish to install.
- Once the page refreshes to confirm the change, restart the server.

This will install the selected Forge version. Note that when you run one of the Forge options it will completely wipe the contents of the mods and config folders (to avoid version conflicts etc...) so make sure you are installing Forge by itself first before installing your mods!

Please note that if you delete the jar folder, or it's contents, the server will reinstall Forge on the next restart which will again wipe the mods and config folders.

Step By Step on Installing Custom Forge Builds

First, download the build you need from: - Make sure to select the specific version you need (as, for example, Forge 1.7.10 mods will only work with a Forge 1.17.10 server):

And to download the 'Installer' file for that version (For these examples we will use the current latest version of 1.16.5 - Use whichever build/version you require):

Once downloaded, double click the .jar file to start setup process:

You will be given 3 options in the window that opens - select "Install server," then select the directory to by clicking the "..." button at the bottom. Then click OK and let it complete the process and click OK on the pop up that comes up when it is done installing.

Once it is finished, you should find the server files in the directory you set it to install to:

In this example I installed the files to the same directory the installer was in the highlighted files (the installer jar, the .log and in newer versions that have it the <version>.json file) can be deleted at this stage.

Upload both .jar files (Forge and Vanilla MC - not the installer file) and the libraries folder to your server's jar directory via FileZilla - Make sure to remove all previous files from the jar folder first to avoid any issues - So you should have something like this:

(Note that you will likely have more folders listed in the top panel, the example server used's files had been wiped prior to the Forge installation - it is just to show that they are placed inside the jar directory)

You will now need to rename the Forge jar accordingly - if you wish to use Java 8 you need to rename the Forge jar to custom_server.jar, and if you wish to use Java 16 (most Forge versions require this and do not work with Java 16) rename the Forge jar to custom_server_j16.jar.
For this example I have renamed the jar for Java 8, as Forge 1.16.5 does not support Java 16:

Now go to your servers control panel and change the drop down list to the correct Custom Server JAR option at the top of the list:

And once the page has refreshed to confirm this selection - start the server up!


Installing your mods once Forge is set up

Now you can download your favorite mods and simply upload the zip/jar files for them to the "mods" folder of your server to install them (via FileZilla as above). Make sure to pay attention to the version of Forge the mods you want to install are using and make sure you have the correct version of Forge the mod needs. Note that not every mod installs via the above method, so always make sure to read the full directions for the particular mod you are installing.

If the mods work properly, your server should start up.

Tip: Install mods one at a time (including any dependancies for that mod) so that you can always determine if a single mod is the cause of your server not working.
Once the mods you wish to use are installed and working fine, it is recommended to shut it down and then follow these steps to load a new world generated by those mods specifically:
- Enter a new world name in the World box (can be anything, just not the name of a world that has already been created unless you are uploading your own world folder for it to load).
- Hit Save at the bottom of the page.
Then if you are using a world generation mod that requires a specific level-type (for this example lets say you have installed Biomes O Plenty) follow these steps too:
- Go to Files > Config Files on your control panel and open the Server Settings.
- Change the level-type option to what your mod requires (for Biomes O Plenty for example, change it to BIOMESOP all in capitals).
- Save changes to the file.
Then start the server back up to load a new world up, generated specifically by the mods you are using (so all natural ores/mods/buildings etc... are spawned correctly).

**Note: As with any mods, the client side is required to be modded as well (with the same version mods) for you to be able to join a modded server. There are various guides and videos on how to do this - a quick Google will provide the information needed.

**Note that some mods are clientside-only, or singleplayer-only and cannot be used on the server!
Clientside only mods will work fine if they are installed on your launcher but not on the server, and will crash the server if installed on it (examples being HUD mods, most minimap mods or Optifine).
Singleplayer only mods simply cannot be used with a server at all. It is rare for a mod to be singleplayer only any more, but this can come up here and there.
