Can't login when accessing /admin

Yes, I can login that way, too, but that's just another way to get to "?q=user" is it not?

The problem is that I've clearly left something out (or mis-referenced something) in my sub-theme. Going to /admin and trying to login brings me no satisfaction.

Yeah, it is weird. It's true for both the subthemes that I've built. Let me explain the scenario:

I run my subthemes as the site theme, with another stock theme as the admin theme (typically my themes look more like normal websites than drupal websites, therefore they don't allow the width necessary for most parts of the admin section).

Going to "/admin" brings up a form in which the user may login (with the admin theme), just as you'd expect. But when the form is submitted, "?destination=admin" shows up in the address bar, and you see the front page with the subtheme. The user has not been logged in, and going to "/admin" will take you back to square one. This occurs not only with the two subthemes I've built, but also with the zen-classic subtheme, and so now I'm assuming it's actually a bug rather than an error on my part. The bug is not apparent when the main Zen theme is selected as site theme.

Let me know if you need more information to help squash this bug!

No, it works when using Garland as the default theme and Blue Marine as the admin theme. It's a problem with a subtheme being selected as site theme, because like I said earlier, the bug is not apparent when the main Zen theme is selected as site theme.

For some reason, at least on my development platform (which is nearly identical to the production server I use), the login never completes. I can't figure this out at all. Is there anything I should be looking for to fix this? (I'm also willing to accept that something is wrong with my localhost setup, but I'm not sure what could be breaking the login...)

When I complete the steps in #5, the bug is still apparent. It seems to be ONLY apparent when a zen sub-theme is selected as the main theme and anything else is the admin theme. (I'm away from my computer right now, but I'll test later if it occurs when the zen sub-theme is the main theme AND the admin theme.)

I've got to open this issue back up. Is no one else experiencing this? It does not occur when using any other combination of themes except for what I detailed in #6 above. Now one of the sites is deployed on a (completely different) production server, and the same thing occurs.

Right, I can login from /user. That one works, but not /admin.

to be honest with you, I've become so frustrated with the level of work required to get Drupal to just behave (and that's all before the hours of work needed to add finesse), I've just switched over to using Expression Engine. We'll see how that goes.
