Problem:
This webpage has a redirect loop wp admin or ErrorDocument to handle the request wordpress(404 Not Found)
Solution is:
I created a fresh .htaccess file, with permissions set to 644 and the following code or you can edit your .htaccess:
RewriteEngine on
<IfModule mod_rewrite.c>
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
