RAD3 modpack not starting on my server

There's still client-side mods being loaded

Do you have radenchants and controllable installed (also maybe another called framework)?

Rename the radenchants and controllable mods from .jar to .jar.disabled and see if the server will start after that

Specifically, Controllable is trying to load Toasts (which are small pop-up notifications you see on the client)

and radenchants is trying to use blaze3d to render graphics (because its meant for client)

thanks, it was controllable and radenchants-it's a bummer i wasn't able to use radenchants but server starts now

Happy to help
