To fix this you have to go to your world in the server folder and delete the folder called "RedstoneEther".
After that replace your "mods" folder in your server folder with a new "mods" folder from
a new server(with the same version).
Keep in mind - all your wireless retrievers and receivers will be lost!!!!!!!
Hope this comment isn't too late to help you!
