Thanks, both NogDog & Maxxd, that's my new theme, the 2020, and theme editor shows "one error" and when I scroll through some of the coding, a lot of warning signs/exclamation marks appear next to some of the lines. But there is an option to "fix now" the "one error" though my site may break. I'll back it up and give it a try. I hope it works.
Well, the theme error fixed "successfully," but when I went to cPanel and changed PHP to 7.2 and logged back on to my site, I was welcomed with 2 Fatal Errors:

Should I try a different theme? WP's 2017 theme got a lot of good reviews. I think I'll try it and see what happens. Thanks!
