I recently made a server using paper, and like any player would, I opped myself through the console and joined for the first time. I then proceeded to create a spawn for my players. To my surprise, I couldn’t place blocks. To further intrigue me, I could break blocks. And the weirdest part of all? I am fully opped on the server and all other commands work fine. It is simply breaking blocks that the server will not allow. No error messages, no explanation, I simply could not place blocks. Everytime I placed one it would disappear immediately. Please help!
EDIT: Not sure what happened, I restarted my server multiple times before when I first had this problem, and I hadn’t changed anything since. Today, when I started up my server and joined, I was magically able to place blocks! Sorry for the inconvenience and thank you all for your help!
