Minecraft Spigot 1.8 Server Issues?

I was making a Minecraft Spigot 1.8 Server a couple minutes ago and I managed to do it all. I typed op (username) in the start file and i was opped, The plugins showed up and I was able to use commands such as //wand but I couldnt break blocks or go to creative mode or even do /help but funny enough I could do /toggledownfall, anyone know what the problem is?
