Been grinding my face on this error that my server keeps running into for idk how long and cant make heads or tales of it.

Can you send me your config file of CreativeCore and ItemPhysic?

https://pastebin.com/gZQ2rQpf

You cannot disable things by using slashes, just remove the lines entirely and remove the latest comma:

"ignitingItems": {
      "entries": [
        "{material:\"minecraft:flowing_lava\",count:1,id:\"material\"}"
      ],
      "isWhitelist": true

I haven't even opened them yet... but ok
...
uh... its titled creativecore-client and formatted as a JSON¿
it just states
{
"use-stencil": true,
"use-optifine-compat": true
}

ItemPhysic is also formatted JSON, witch cant be uploaded

Maybe use pastebin.com for the ItemPhysic config file.

Yeah, but also json might not be the best config file format. I might change it in the future.

..........
