I have updated the plugins etc to allow the nether to be there.
Please be aware that it is not possible to place portals in the nether to avoid the destruction of real-world structures with the corresponding gate that would be created. Therefore all the gates in the real world come out at the same one in the nether and there can be only one gate in nether that will always point to spawn.
Also, please tell me if you have lag while people are in the nether. Due to the updates the lag should be gone but I want to make sure.
