If you did, restore it using FTP/ SFTP , or your web-host’s cPanel or whatever file management application your host provides (no Dashboard access required).

If not, replace it with a fresh copy

Alternately, ask your hosting provider if they a backup of your site. If they do, ask them to restore it

I still have the problem though of having the line about “…proudly powered by…” at the bottom of each page and post. I’d really like to get rid of this, so that the website looks cleaner. Nothing I’ve tried (that I’ve seen mentioned on other forum threads) seems to help.

Is there a simple way to remove this from my website?

Thanks for your patience and help.

That’s probably coming from one of the templates of your theme’s (e.g., footer.php …)

What theme are you using?
Downloaded from?
