Thank you, Moshu. I would be happy to start over again.
I downloaded the theme, as I was advised, once I was told to click on the word “Cutline”, and it was explained to me what I needed to look for.
Then I revisited the WordPress instructions on installing a theme. Since I was replacing the same theme, I thought I needed to deleted the old, corrupted theme first. So I deleted it. Then I uploaded the zip file to the theme folder in wp-content, and extracted the contents, per the WP instructions.
Now the instructions tell me to go to the Administration Panel on my blog. But my blog is blank. So how do I access my admin panel?
I’m sorry things got out of hand, but your volunteer needs to realize that not everyone lives and breathes WP. She could have been more clear. That’s all. Now I’ll try to behave.
