Duplicate Mods

If your modded setup is crashing and the console is showing an error that contains [SEVERE Found a duplicate mod] this specifically means that there are two files in the mods folder for the same mod.

The same mod cannot be loaded twice - whether it's the same version for both files or different versions of the mod. The errors should state which files/mods are the cause of the problem, you simply need to go into the servers mods folder and delete one of the files before restarting the server.
