So, my issue is the title of the post. I have: -given myself op level 4 -removed all plugins from the server -am in gamemode 1 -set command blocks to true in server.properties I am using spigot 1.14.4. Opped, in creative mode, command blocks enabled, no plugins, away from spawn, still unable to place them. If I place them with /setblock, I cannot open them either. Any advice on what to do? I'm feeling really stuck.
