Bulding the web site in a demo that comes with the bridge theme

I am trying to build my site in wordpress, and installed the bridge theme that I bought, started it in a demo that comes with it, wich is called “hosting”, and when I set it, the top banner or slider on the header doesn´t appear, and appears an error in a red sign. Can any body help me solve that problem? I would be really happy if some body do solve that problem for me.

Have you activated the slider plugin?

Further to activating the plugin you probably have to import demo slider content and maybe assign the correct slider to the page.

Most likely this will all be in the documentation with the theme

Yes, I did activate it
