Solved I can't build?

Hi, I almost finished making my server and was going to build a spawn. When I place blocks it removes it right away, but I can destroy blocks.
It's not in adventure mode it's in creative and there is no error message when this happens.
Thanks for reading and I hope you answer my question.

 

try OP yourself by typing "op username" on console.

 

Already tried that, still nothing happens.

*friendly bump*

Hey there,

Hmm. I'm not sure why its doing that. What you could do is build a spawn area away from the current spawn. And then presuming you have essentials installed, you could use /setspawn..

 

I can destroy blocks, not place blocks.

>>>>I CAN DESTROY BLOCKS ANY WHERE<<<<
but not place blocks.

 

Plugin List?

 

I'm having the same issue with blocks disappearing. All plugins are disabled so they are not causing it.

 

Are you definitely op and not in the 16 block spawn radius?

 

It was the 16 block spawn radius! I have to go back to admin school. Thanks! I wish I hadn't deleted the region file. I thought it was corrupted.

 

I went far far away, and I place blocks and they disappear and appear in my hot bar again.
I even when to another world and still happens

Wait, I removed all plugins and I can place blocks.
So it is with a plugin...ill investigate.

I asked, what is your plugin list... I might be able to tell you which one if so.

 

It's a plugin called "SimpleZones", I can build now.
