hey everyone I am trying to run a crundeecraft server using AtLauncher and a website called minecraft-hosting.pro, I checked to see that they are both the same version (1.1.0) but I got an error saying FML Mod Rejection for the Ender Storage mod,so I said no problem, I used Filezilla to copy the ender storage mod from the AtLauncher folder to the server folder so the mods are compatible, after doing that, I now get an error saying Fatally missing blocks and items. What do i do?
