Forgive me ignorance, here. I have never moved a Silverstripe site, and apparently, I broke something.
Steps I took:
-backup db on old host
-download files from web directory on old host
-restore database to new host
-download new stable release (2.3.5). I was running 2.3.3 on old host, but foolishly, I don't have the whole package anymore and thought 2.3.5 would be fine (maybe that was a bad idea)
-copy new release to new host web dir
-run install with new host db credentials, location, and same admin credentials as the old host
-copy customized folders from old site to new web dir
When I browse to the new host site, the site looks great. However, when i try to log in, there's really no response. The page refreshes (and the url changes to 'site.com/Security/login#MemberLoginForm_LoginForm_tab', but I get no error message and no entry.
