Another post mentions that if BPS Pro is installed on a domain in the root then all other domains below the root must have their own .htaccess file. My host requires primary domains be installed (automatically) in the root, so I cannot assign the domain to its own folder and will have to install .htaccess file for all the other non-root domains.
Would you describe in detail how this is done, and how do I install BPS Pro in non-primary domains?
