abccookie on "403 on wp-admin"

I was trying to log into http://www.bellowswalpoleinn.com two days ago but I keep getting a 403 Forbidden page. I did not update Wordpress the day before I got the warning and I don't remember getting an alert to update either. I assume it is up to date. I went to wp-admin but got this:

403 Forbidden
You don't have permission to access /wp-login.php on this server.

The website looks and functions fine, but I can't access the dashboard. I have checked out similar problems and solution suggestions on here, but none have worked. Mainly I read a lot of suggestions to tinker with the .htaccess. In the root, I found the .htaccess in a "public_html" folder that houses the Wordpress stuff. I copied that file into the wp_admin folder and into the root as well. Tried deleting them from each to see if it would fix the problem but no luck so far.

I have no idea where to go from here. If anyone else has other suggestions, I'd like to hear it. I did not set up this website. It has simply been passed on to me to manage.

Inside the .htaccess file, if it helps:

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

# END WordPress
