Need Help with Silab

Okay, so I've been going on some servers with Silab, but then the Silab items don't even work. The capes, godswords, and armor all end up being different items other than what they're supposed to be, can anyone help?

 

1 Do u got silab 5.0 try using the site www.client.silabsoft.org that should help and is the server coded correclty? (not a cheap made server)

That should do it i think
