Redstone Walls lets you create controllable walls that can be dynamically any height. Useful for doors, walls, and even protection.
There is! plugins/RSWalls/settings.yml. This file will let you change the marker block, the wall block and a toggleable true/false if you want the smoke effect.
Did you change your configuration to use different block values? Are there any errors in console? Do you have a World Protection plugin preventing the blocks from spawning? Did you align the marker blocks properly? Take all of these into consideration before making a comment.
