Hi Francesca,

I have fixed the problem with the backend.

About the frontend, there are 2 javascript errors in your website caused by another extension or template.

For now, I have disabled the grid modules.

You must fix these 2 errors before enabling the grid modules.

There were some leftover files required for the old K2 version.

These filese were not needed anymore but would create the error. I have deleted them and from now on you won't have any problem.
