Someone help

[TheMCSparky]

Me and my friends noticed some weird things going on in my server. We are not able to craft some stuff but it shows up in NEI. We have tried direwolf and Mindcrack and cant seem to make long fall boots and elevator tracks or arcane wood blocks can anyone help?

When arent able to make the elevator rails since we cant make advance rails for some reason :/

Make sure that your server and your client are both using the same config files.
