I cannot edit with the code in other worlds and in my own worlds.
All types of blocks, decorations, and backgrounds cannot be placed, yet other game buttons work (like god mode, settings, etc.)

I have tried everything I can think of:

restarting the game,
going into other worlds,
Restarted my computer and cleared my browser cache (I was that desperate)

Does anyone have any ideas of how it can be fixed?

EDIT:

Not sure why, but it just started working again when someone gave me the code to their world.

If there are any working solutions, I would still like to know what they are in case this happens again or someone else stumbles upon this thread.
