Yeah, I think I know what's happened here. If you type /sms get submenus.back_item.material, does it say wooden_door ?

The problem is that when SMS parses wooden_door, it's getting the block version of the wooden door (block ID 64). This was OK in 1.6.x but Mojang removed the textures for quite a few block materials in 1.7.x (see http://minecraft.gamepedia.com/Data_values - any light blue material has no texture any more and can't be obtained in any way).

To fix the problem for now, just do /sms set submenus.back_item.material wood_door - that will force the use of the item version of the wooden door (the block version is called 'wooden_door', the item version is 'wood_door').

Next version of SMS will ensure the item version 'wood_door' is the default in the config.yml.
