festy theme not stable

I just purchased the Festy theme from theme forest and i am not able to change the logo (its default Festy logo), even tho i changed it in Customize>Logo …still no effect.

Then i created a duplicate page and now the new page doesnt show any images , only shows text.

Can anyone help with this.
