404 error after trying to change hosts

I had my site on https://www.testsite.com/wp/
And I wanted to move to a new server and new domain https://www.newsite.com
I messed it up on the new site, so I just went back to old site for now. But for some reason my content pages are giving me a 404 error though everything else is working.

This is my htaccess I don’t know if I messed something up on there or what else it could be.
