I have reviewed the instructions at:
However, I cannot access the file without 'admin' privileges. I am attempting to login to SFTP using one of the users created when a domain was created, which I assume is a problem. So, how do I login ... with what user name? I see no other user mentioned anywhere in Control Panel, unless I go to the bottom to my account, and then in there at the top of the page there is mention of what I assume is a user name that was assigned when I opened an acct with DreamHost. Is that the username I would have to use? If so, I never have used it before and don't remember a password for it, and see nowhere to reset or retrieve a lost password. The only option to change a password for that account, that I see, says that it will not change anything but the password to access the web interface at panel.dreamhost.com.
Hopefully someone might be able to assist with this whilst I await a ticket reply from support. I submitted a ticket because the live chat said they are experiencing a high volume of requests, and the wait time was "0 minute," but after waiting a few minutes I decided to just submit a ticket anyway.
P.S. As I have about 15 sites all using nearly identical .htaccess rules, I figured it would make more sense to just move most of them into httpd.conf instead - such as rules to block IP ranges that I want blocked.
