I've decided that I want to let the community know when I fix an issue on Prism, starting with this one.
Prism has been plagued by the inability of members to create nether portals. Thankfully Sora has been so kind to help me troubleshoot, and ended up finding the issue. Make sure to thank him for his role is fixing this issue!
Now, everyone should be able to create nether portals without problem, but if an issue arises feel free to leave a response or Private Message me.
