Thank you for your thorough and thoughtful reply. I have come to understand all of this in more detail as I have progressed, and even though there has been hacking on many levels on my site and actually many attempts per day (the powers that be don’t appear to like its content), I now realise that iThemes updates htaccess regularly. My working solution is to hold a clean version of my site and regularly delete the existing version and reload it. A fast link helps… This seems to be working.
Kind Regards,
Richard
