The template is nowhere close to what the have in the demo

The template looks nowhere near what we’ve been offered in the demo Template. Any solution, please?

Themes do not look the same until it has been configured and setup beyond just installing,

You need to install plugins, add demo content etc.

Bear in mind that images are almost certainly not included and will be using place holders.

Check the item documentation which will explain the process

First you must import demo content and required plugins .
Sometime images are for demo purposes only.
