Can't use blog after renaming directory

I currently have WordPress installed in a subdirectory. I wanted to change the url (let’s say, from ‘site.com/blog1’ to ‘site.com/blog2), so I renamed the home and site urls under settings, and then simply renamed the directory to ‘blog2’.

After that, content doesn’t load, showing a blank page and wp-admin redirects me to wp-login, which sends me back to wp-login whenever I try to log in.

I’ve tried defining the urls on wp-config, renaming them on the DB, renaming the theme so it defaults, disabling plugins, removing (renaming) .htaccess, and probably more things I can′t recall right now.

I’ve been trying to fix this for a couple days now to no avail. Any help is appreciated.
