"it looks like you are using an unsupported modified version of the game" error

[Samv2005]

Whenever i try to load into a world with a small mod-pack i made i get this error: "it looks like you are using an unsupported modified version of the game". Then below that i have this error:

The game crashed whilst exception in server tick loop
The game crashed whilst exception in server tick loop
Error: java.lang.NoSuchMethodError: net.minecraft.entity.EntityLiving$SpawnPlacementType.canSpawnAt(Lnet/minecraft/world/World;Lnet/minecraft/util/math/BlockPos;)Z

is there anything i can do about this? i checked and all the mods are the correct version.

is this what you needed?

Crash report.txt

[Cadiboo]

You posted your crash report as a downloadable file. I asked for your entire debug log as a PasteBin or GitHub Gist link.

Try removing EnderCore

[quadraxis]

Update your Forge version.

[Samv2005]

few things:1: for some reason now it says "the game has crashed, sorry for the inconvenience. 2: now it loads in then before the chunks load the game crashes, and 3: i don't know how to get the debug log

 

P.S.

I also tried updating forge but that didn't do anything

i mean like i dont know how to find it

[Cadiboo]

your log will be in .minecraft/logs/

[Samv2005]

i looked and theres nothing helpful there

[DaemonUmbra]

What launcher are you using?

[quadraxis]

Does it work without Optifine?

[Samv2005]

ok turns out 1: im an idiot and didn't scroll down in the logs folder 2: the problem was i needed a new optifine version, or something like that and 3: my fps is super low, even with optifine fast graphics, etc. Is there a way i can increase it?

Edited October 17, 2018 by Samv2005

[Samv2005]

for better fps?

the game is working now, its just super laggy

Your probably going to want to give it more RAM (your giving it 1gb, I recommend about 3gb). This is probably your main issue.

You could also try removing some of the mods that are throwing errors (solarflux, mysticalagriculture).

[Samv2005]

well i have solar flux for power and everything i have is centered around mystical agriculture so should i just get a different version of those mods?

 

[Cadiboo]

Getting a more updated version will probably help but
