How Can I correct Broken WordPress Permalinks

Looks like your .htaccess file was overwritten. Simplest solution is to change the permalink setting back to page_id and then again to Post name it should overwrite .htaccess file, if php error not try to put that into your .htaccess:

# BEGIN WordPress # The directives (lines) between "BEGIN WordPress" and "END WordPress" are # dynamically generated, and should only be modified via WordPress filters. # Any changes to the directives between these markers will be overwritten. <IfModule mod_rewrite.c> RewriteEngine On RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}] RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule>  # END WordPress 

If its just about accessing all pages with adding index.php php error in url then simply you can use custom permalink structure to allow WP to do this.

You mension that its showing page_id in place of name so php error in permalink you can use %postname for his. take a look on screenshot.

after doing this change your url will work same as you asked.
