Bug HELP !!! Cant Use Certain Blocks !!!!

What does it say when you type /ver ?

 

You are probably using an old spigot version that is 1.8 but not. Try using one of the newer jars

 

Update your Spigot version, you must be using a 1.7 version. All the items you listed are 1.8 items and are not in 1.7.
Asuming you're on a 1.8 client, and trying to place the items and they either turn into other things or just disappear, you're probably on spigot protocol hack / spigot 1649.

Use buildtools and get a 1.8 version.

 

That's your problem, all blocks you are having problems with are 1.8 blocks

 

Yea, your server is 1.7, so you can't use 1.8 blocks. You will need to update to spigot 1.8.
