Hello?? Any WordPress hotshots out there? This problem is ALL over the Support forums, and it is clearly a bug. NONE of the fix-it suggestions have worked on a clean, new install of WordPress with NO plugins, extra themes, nada, zero, zip. As per everyone else, wp-login.php brings up the correct login panel, but once filled out with user name and password, returns a blank wp-login.php. Viewing page source shows no code. This happens in both Firefox 2.0.0.3 and IE 7 fully patched. Navigating to any other page in the /wp-admin/ returns “???” with no code visible via viewing page source. Hey WordPress – this is TOO COMMON a problem to ignore, and deleting plugins and renaming directories – if I HAD any to delete or rename – is a shameful way to solve things. FIX IT.
