Moved my site. Can’t access it.

Not sure how to label this one.

So, I was getting an internal error message when people tried to access my website, https://www.windowdepotva.com/site. Thing was, my host only allowed so many forwards from windowdepotva.com to windowdepotva.com/site.

I moved the necessary folders from the “site” folder, to the root, so the site would appear, when you visit windowdepotva.com. I also removed the redirect set in place.

Problem is, when I access https://www.windowdepotva.com, the css from the theme isn’t registering. I believe the issues is because, in settings, I have to document the website, and I still have https://www.windowdepotva.com/site. I need to get into admin and update the listed site. Thing is, when I try to access my wp-admin or wp-login pages and hit enter, it redirects me to https://www.windowdepotva.com/site/wp-admin or wp-login. Is there anyway, I can update the settings through FTP???
