Crashing on world start

https://pastebin.com/5vpyhJmD

I’m having problems loading up.

I am using modpack Magiculture 2. I’m also have this same issue with RAD. Any known fixes?

There is a incompatibly with sponge and another mod

Caused by: java.lang.ClassCastException: net.minecraft.potion.Potion cannot be cast to

Sadly i can not tell you what mod it is. If you tell me your mods I maybe able to work it out from there, however if not then try backing up your server and then removing all mods but sponge and slowly add each mod back until the crash happens again
