Troubleshooting 'Monoconfig not found' Error
If you are getting the error 'monoconfig not found' when trying to start up your tModLoader instance, you will just need to install vanilla Terraria with the One Click Installer, and then install tModLoader over that.
First, just go to the One Click Installer, and select Official Terraria from the catalog.
Once that has been installed, you can then go back to the One Click Installer and Install tModLoader the same way, this time using the
overwrite installation method.
Once that is complete, you're done!
If you are still having issues starting up your tModLoader server, don't hesitate to contact our support team!
