Ho necessità di usare un tema che è stato usato per un dominio scaduto. Qualcuno mi può aiutare?
You came all the way here but you decided to post in Spanish??/Portuguese? 
- it’s Italian
- I was asking for the solution to my problem to some of my compatriots
- my English is not that great
It’d be better if you post it in here in English, you don’t need to be a language expert but you could use translation.
Anyway, if you’re looking for help related to the theme you have purchased, you need to contact the item author for the support.
