host doesn't allow .htaccess, site transfer

[shawn_a]

well if it doesnt support htaccess and you got the apache warning ( which is there for a reason ) Then your site is probably wide open for attacks, and your user files might even be viewable from the web.

People are running on IIS but you have to handle security yourself.

Try turning debug mode on and see if you can find out why logins are failing, also check
data/other/logs/error log
