demo version problem with a tool

Hi guys,

I bought a theme and follow the instruction on the documentation to install it and upload my content. The used css to have it as I wanted. The problem is that the dont explain how to take off a little color tool on the left that is relevant only on the demo.

I guess I should just find it on the PHP files and delete it. But as I am not familiar with php I am having troubles. Can anyone help me, please?
