My domain www.barcelonacookingworkshops.com is pointing to my donain/website www.barcelonacuisine.com

When I search www.barcelonacookingworkshops.com it does not go to www.barcelonacuisine.com

The search engine shows an error.

A few weeks ago it was landing on www.barcelonacuisine.com now it's not.

Please help me resolve this.

I want my domain  www.barcelonacookingworkshops.com to land on www.barcelonacuisine.com
