Is modded items even compatible??? Because config exists so i guess you can put modded item to make them glow but how?? The mod i want to make glow is hardcore torches, so i put the lines there's, and now when joining world its not responding, am i doing something wrong?

The last commas in lines 4 and 8 may have to go. The final items in a json list do not have comma after them.

Otherwise post the error log you get from MC.
