# How to Fix Mod Compatibility Issues

Mod compatibility issues are common when running modded Minecraft servers. This guide helps you identify, diagnose, and resolve mod conflicts using HostByte's Game Panel. 🛠️

## ⚙️ What are Mod Compatibility Issues?

Mod compatibility issues occur when:

* ✅ **Mods Conflict** - Two or more mods interfere with each other
* ✅ **Version Mismatch** - Mods require different Minecraft versions
* ✅ **Missing Dependencies** - Required libraries are not installed
* ✅ **Load Order Problems** - Mods load in the wrong sequence
* ✅ **Resource Conflicts** - Mods use the same resources or IDs
