WP index stuck on first post, cannot redirect to newest post

Hello,

I made a mistake today and thought fixed it but from there other things went wrong and I cannot seem to find the answer, so I hope to find some help here.

Today I “brilliantly” decided to change the general URL settings and to add “WWW” to the location of the WP folder and my site and lost the blog & admin. I fixed the subsequent lost admin access with a solution from here to add 2 lines to the function file in the themes folder, put the URL’s back, removed the 2 lines from the function file and everything seemed ok. (I double checked if the file was in its original state afterwards).

Two things happened, suddenly I got an .htaccess file in “blog” and my own .htaccess file at the root of my site was modified by WP.
I think the trouble may be there.

I’ve WP installed in “https://(www).my_site.com/site/blog/”.

Firstly if I go to https://(www).my_site.com/site/blog/ it loads my very first post from 2011. It’s *not* pinned, and if I remove it by making it “private” the previous URL leads to a WP “page not found” page. Secondly the FeedBurner page is just loading the entire first post from 2011 with skin and such. So I think there’s something pointing somewhere to the wrong file or directory. I just for the life of me cannot find it.

Not sure if this helps but this is the code from the .ht file in my blog folder:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /site/blog/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /site/blog/index.php [L]
</IfModule>

# END WordPress

And this from my sites root .ht file:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /site/blog/index.php [L]
</IfModule>

# END WordPress

I did some reading on .htaccess and Apache but it remains largely a mystery to me.
Any help would be really appreciated.

Just feeling so dumb I messed with something that worked flawlessly before. /o\
If it ain’t broken…
