Thank you! THANK YOU!
I was able to temporarily update my functions.php to get back into my admin, where I fixed the URLs.
However, now I can’t see my site anymore, I’m receiving this error when I go to any page in my URL:
Fatal error: Call to undefined function get_header() in /data/23/3/100/84/3100247/user/3454874/htdocs/wordpress/index.php on line 1
Could my URL mistake have altered the index file?
