I can't figure it out please help

Dooglamoocities, just enough items, minecolonies, overlord, and viescraft-airships. but it throws the same errors when i remove everything but rftools, compatlayer, and mcjtylib.

I need the exact versions

rftools-1.1x-5.71, compatlayer-1.10-0.1.3, mcjtylib-1.1x-2.3.1, ViesCraft-4.0.1a-mc1.11.0, Overlord-1.11-2.0.1, minecolonies-universal-1.11-0.6.2020, jei_1.11-4.0.5.203, and dooglamoocitiesmod-1.11-1.3.

deleted and redownloaded the rftools, compatlayer, and mcjtylib (for the third time) and it works now.

You were using the wrong version of compatlayer. i.e. the one for 1.10

What mods do you have?
