I'm stumped. I created a subdomain (http://students.teryg.net) a couple of months ago, and have been using it since. Last week, I needed to move its contents and temporarily change things so students.teryg.net redirects to http://www.teryg.net/wesley/webdesign/fall2007_projects/ .
The move went smoothly enough, but students.teryg.net reverted to an index page it had two months ago. I've tried three different browsers, refreshing, reloading, emptying caches. I've tried html, php, and .htaccess redirects. I've tried using the ftp access on the dreamhost domain maintenance page to replace the contents of index.html.
I finally deleted the subdomain in dreamhost's domain management page. Caused an error message, but at least the old information was gone. I waited 24 hours, then went back into management and recreated the subdomain. I do need it! It went right back to that page from a couple of months ago. Looking around my webspace, I can't even find the code for that page out there.
I've got to be missing something obvious. Anyone have any ideas?
