First steps

Finding your Forge/Minecraft version

The most important step when installing mods locally (or to a server) is checking that the mod is supported on both the Minecraft version and Forge version that the modpack uses.

• You can find the modpack's Minecraft version (in most launchers) in the pack/instance description.
• You can find the modpack’s Forge version (in most launchers) by opening the packs advanced information panel or in the pack/instance description.

For example, the Twitch launcher displays the Minecraft version at the top of the mods list for the modpack and the Forge version can be seen in the window that opens when unlocking your pack to add mods.

Example mod

Storage Drawers is a popular mod that is used in a lot of Minecraft modpacks across a range of Minecraft and Forge versions.
You will need to download the correct version of it from your site of choice. We recommend Curseforge.

• Check the mod version is a Release and not Beta or Alpha .
• Check the mod supports the Minecraft version that the modpack is running.
• Check the Forge version requirements of the mod.

Here is the Storage Drawers mod overview page on Curseforge: Storage Drawers on CurseForge

Selecting the tab will display a variety of versions and options for the Mod: Storage Drawers Files

Double-check that the file you select and download is the correct one for the modpacks Minecraft version and Forge version.

Adding the mods to your modded Minecraft server

Mods can also be added to packs that run in multi-player environments on servers.
This alternate article shows the steps required using either the Multicraft control panel or alternative FTP software. How to: Adding additional mods to your modded Minecraft server

Troubleshooting

When adding mods to existing modpacks there is a chance that something will go wrong, these are some of the most common issues that occur.

Keep in mind that some mod authors will have customised and adjusted their pack to work exclusively or in a more integrated way with the mods that it comes with when installed and support for additional mods may not exist.

IndexoutofBoundsException

This error may relate to an issue with the configuration files of the new mods. The quickest way to test this as the cause is to delete the configuration files of the mods that were added and then run the modpack again to allow new configurations to generate.

If this doesn’t work, the error is being caused by something else.

Firstly check the issue tracker, bug reports and comments sections for the mod to see if it is a common error or unique to you.
If you do not find a solution, open a support ticket with the mod author giving details of the error.

MissingModsException

This error is an indication that either the mods list on your local computer and the server aren’t the same as each other or that the mods in them have different versions.

Usually, this error will be accompanied by a mod and version number. Make a note of this before checking your local files and your server files for that mod to make sure they match.

Occassionally a crash may be a little more in-depth and related to a specific mod being broken or some other more technical issue.
We always recommend checking the mod's support, issues and comments pages to see if anyone else has suffered the error and potentially found a solution.
As well as sending a message or opening a ticket with the mod author if a fix is not clear.
