I have a problem.
I have installed a very large minecraft modpack but since the better foliage mod is in there (downloaded from curse forge) minecraft simply does not start so I press start but the window does not open and the debug log just does not work after a short time I have the same problem with the item physiks mod.
Is the mod compatible with your version of Forge?
I'm not sure so far I've tried the newest and two slightly older ones
Then download a compatible version of the mod (must match the Forge version)
There are only three on curse forge
Then you have to search on other sites.
