I made a modpack for me and my friends and have already sorted out a series of problems but there is one that I have been trying to fix and cant. Whenever I load up my modpack it comes up with Mojang followed by a white screen, I go into Forgemodloader-client, everything is fine apart from this:
[WARNING] [mC] Problem occurred in default config writing.
Someone please help as I don't know what happened!!!
