This error has happened with mods and without. This is with forge 1.7.10.
I have no idea what the issue is and I'm really frustrated.
Like I said this also happens when there are no mods in the mods folder also. The EULA is correct and all the missing files that it says it cant find are there.
Are you using a hosting service, or local host?
This is not a localhost I'm using my dedicated box.
Can I see the crash report?
Yeah here it is http://pastebin.com/PYm43Gkd
I have tried deleting all the .jsons but nothing has come of it.
