1.12.2 Fatally missing registry entries

[zwartebliksem]

So I just started a new server and I tried to install some mods but when I try to log in it says 'Fatally missing registry entries.' First thing I did was look it up of course but most of the solutions that other people tried didn't work for me.

These are all the mods I'm using: Armourers workshop, chunk animator, custom main menu, custom npc's, forgelin, hammercore, improvable skills, just enough items, librarian lib, lycanites mobs, mo bends, no recipe book, open blocks, open mods lib, optifine, ore lib, saomc lib, sao ui, tfa, xaeros minimap.

Also do I only gotta add the server sided mods or also the client sided mods?

Post debug.log from server and client.

Forge has a mechanism so that client-only mods will not load on a server, so it should be safe to install all mods on the server.

However most client-only mods do not indicate this to Forge, so Forge will try to load them anyways and the mod will crash.
