I have a site for a few years, I had the BeTheme license, I had to renew it because we deleted the API key.
I bought the same theme (BeTheme), I downloaded the .zip file
But I don't know how to install it, I'm new in this field and I absolutely need help.
My site has lost all its identity since 2 weeks and I am afraid to erase everything when I install the theme.
The site in question is: https://corfu-solaire.com/
Thanks in advance,
