Problems with cPanels and WP

(My english is not that good by the way)

So, I’ve been trying to add a new theme to my WordPress website, I bought one named “Wines- Restaurant and bar” and it gave me two .ZIP files.

“Wine”
“Wine-child”

And I can upload without any kind of troubles the second one.

But the first one I just try adding it and this happened:

“Are you sure you wanna do this?

Try again”

So I try using an FTP Program called “File Zilla”.

I did everything and nope, nothing.

So I opened my cPanel and I went to the wp folder

This is the route: public_html/wp/wp-content/themes

I uploaded the files and unzipped them there and nope, nothing.

Help please.
