Moved Site from Subdirectory to Root

Hello All;

I moved my site from a subdirectory to the root. I used the information that can be found at:
https://codex.www.ads-software.com/Giving_WordPress_Its_Own_Directory
However, I did not have the chance to log into the ADMIN interface before had as the move was compulsory. So, now it appears that my site doesn’t have any CSS and I cannot get into the /wp-admin interface to change the Permalinks in the Permalinks panel which I am not sure are setup anyway (don’t remember ever setting those up).
So, now if I try and get into admin via

https://www.thepaddockworks.com/wp-admin
or
https://www.thepaddockworks.com/thepaddockworks.com/wp-admin

It does not work. What if anything I can do without having to reinstall?

The site was originally
https://www.thepaddockworks.com which pointed to public_html/thepaddockworks.com/ directory.

Through the cPanel and hosting setup; thepaddockworks.com now points to the public_html/ directory for SSL purposes and reasons.

I have moved the index.php and edited it.

Everything is the same otherwise. I have copied the index.php and .htaccess files up as suggested by the above instructions.
