My site is visible only in the mobile version

Good evening, I have a website https://www.brighterhome.it/ on which they installed the Umimo template.
Now you can see it in the mobile version also from PC.
I have the purchased code but not the access credentials from the pavothemes area from which they bought it. I also want to extend my license extension to get assistance but I don’t know how to do it.
Can you help me?

Hi,

Contact with your purchase item author hope they will help!

Thanks!
