I'm upgrading an old forum that we use for testing from 7.3.1 to 7.6.0. I got stuck on the first step. When I check files, it says admin/cp_style.css is missing. So I added it. Then it says it needs to be removed and added. I didn't find a copy of admin/cp_styles.css in the 7.6.0.zip file. How do I fix this?
Here's a screenshot:
