McInnit

I just cant pick up items for some reason

Its ok now, I just had to make a new server and then joined my original one now I have op, thanks to everyone who tried helping

Nope, when I do /op McInnit I cant access commands. I've made my friends op to see if they can /op me, but it says that I am already an operator, but I cant do any commands. Even when they deop then op it still doesn't work. Im on Java btw if that helps

im trying to do simple ones, like gamemode creative etc and it wont work. It only works when I put commands in console, but not ingame

I've already done that multiple times, and it still doesn't work. When I made the server, it worked, but now I cant access commands

I made a server, and at the start I made myself op. A few hours later, I'm not able to use commands and says 'I'm sorry, but you do not have permission to perform this command' whenever i do any command. It does not make me op even when I type it in console. I have no idea what to do...
