I had the same thing. ABSPATH stored the entire query string. Like this: ‘https://www.site.com?step=2/’
I don’t know this happens, but it’s fixable.
1. Log into you MySQL using phpMyAdmin.
2. Go to the table wp_options
3. Here you should see that ‘siteurl’ (should be row 1) is screwed up.
4. Press the fancy pen icon and change the value to the actual site name. Leave a strailing slash ‘https://www.superfancywpsite.com/’
5. Find row 39 ‘home’. Change that one too.
Good luck,
