I can't use command blocks!

Command blocks are enabled.
I'm opped.
And it just says when I input a command block 'You must be a opped player in creative mode'.
I keep running into lots of problems! I'm getting quite annoyed now...

 

op yourself and go into creative mode xD

 

I said I was opped AND in creative mode...

 

@JVC_Airtime Make sure you don't have a plugin (WorldGuard or EssentialsAntiBuild to name a few) that blocks commandblock usage for ALL players, including ops. If you do, you should be able to re enable it through their config files.

 

I allowed all players to use blocks but it still doesn't work!

 

Check your server.properties and make sure op-permission-level=4. Had this problem on my server for a while too.

If that doesn't work, list your plugins as a plugin could be affecting it.

 

@JVC_Airtime Make sure in your server.properties file that the op permission level is 4 and make sure you are an op level 4.
