Thanks “not a coder” for coding a solution to this problem! Worked great.
The anonymous post listed above worked perfectly for me. I’m re-posting the contents of the .htaccess file here WITHOUT the line numbers (1. 2. 3. etc.). The code won’t work with the line numbers included.
# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>
# END WordPress
