Bug FTB Infinity Evolved - 1.7.10 - Can't craft item

[dotcom]

Hey,

I'm trying to make advanced solar panels but I can't craft the Iridium-Iron plate - https://ftbwiki.org/Iridium-Iron_Plate. The weird thing is when I'm in the crafting table it shows me the item but I can't drag the plate out the crafting table, it just pulls it back in.

I'm playing on a server. I've checked the configs to see if it's disabled, but no joy.

Restart your game, did you add anything - like optifine?

Nah, I just used Curse. I can craft it in SP but not on my server.

EDIT: Server has been restarted multiple times.
