What is Cauldron? Cauldron is a server jar that allows you to use mods and plugins together on your server.
Do I need Cauldron? If you have a modpack and you wish to use plugins with it then, yes. However, not all modpacks can be used with Cauldron. Contact the modpacks department or our Live Chat support for the specific pack that you have questions about.
How do I get Cauldron? Sadly Cauldron is no longer available for download. If you would like Cauldron installed just submit a ticket to our Modpack department and we will install it for you free of charge.
Installing Cauldron: (Important!) You would install the jar just like you would any other custom jar for your server. You can find more about that here. Cauldron will not work unless you follow the tutorial for custom jars. Following the custom jar tutorial will make sure your server boots up using Cauldron as the server jar. Please view the knowledgebase article forInstalling and Using Custom Jars
Always take a backup when installing Cauldron onto your server!
Plugins Version Due to most modpacks being built around older versions of Minecraft you need to make sure you download the correct version of the plugins. Check what version of Minecraft you Modpack is running and download the correct plugins.
Bare in mind Tekkit Classic does not require Cauldron and can already support plugins.
