Thanks for checking, Paul.
In the end, I had somehow removed my index.html file from my es/ directory. So adding it back in and removing my .htaccess file cleared up my woes.
I have not. Based on past experience, I would not expect much help (iPower), but it is worth a try!
I’m not an htaccess expert by any means. Do you have access to the Apache conf? What it sounds like you need is a VirtualHost setup.
