Can't Connect To My Own "RLCraft" modpack server

Hey guys!

So I tried to join my server, but this error occurred:

Internal Exception: com.google.common.util.concurrent.UncheckedExecutionException: java.lang.IllegalStateException: Recipe minecraft:shield (net.minecraft.item.crafting.ShapedRecipes@553d828a) produces unregistered item minecraft:shield (net.minecraft.item.ItemShield@3f6a9ba0)

(I have all the mods that are in RLCraft installed and I have forge 1.12.2 (14.23.5.2860))

Do any of you know how to fix this?

Thanks!

Here is the Server Log Link: https://mclo.gs/FQfiDED

The server was meant to be for me, my brother, and a couple friends.

How do I share the client log?

I installed them from curseforge.com, not overwolf. and I installed them from the modpack section

ok, I'll try that
