How to setup a server

[OttersMeep]

I can't setup a forge server, when I do, it loads correctly, but I can't place blocks from mods anywhere.

Can you place vanilla blocks? And are all the mods also loaded on the server?

[OttersMeep]

OK, also, thanks for replying so fast!

I can place vanilla blocks, but when I place mod blocks, it disappears. I'm using MC 1.16.4 (current). The mods are loaded, but I can't place any blocks. If it helps, I'm trying to load SecurityCraft. The block appears, but after 1 tick, it's gone. (I timed it, exactly one tick)

Adding more information

I uploaded everything in the logs folder, just in case it helps. Also, I can't run the forge server, it says Illegal Operation

I'm using the official start text in Terminal:

java -Xmx1024M -Xms1024M -jar minecraft_server.1.16.4.jar

I tried running the forge jar, but it doesn't start the server, from the command line or finder. I don't know if you know this yet or not from the applications I'm running, but I'm on MacOS Catalina

OK, but I don't know how to run an older version, Apple downloaded this for me.

What version should I run, and where should I download it?

OK, I am good with installing anyways. Just open the .dmg or .pkg and I'm done.
