I am having a similar issue with WP2.0.2 and FF 1.5. The issue for me is not just logging in, but on my web site, updated content is NEVER showin in FF, only in IE. There is something weird going on with the caching.
If none of the above steps are working, and you feel comfortable manually editing your apache configuration file, you may need to ensure the the AllowOverride directive is not set to “None”. If this directive is “None”, then the .htaccess file is ignored.
Okay, I will try to submit this to the codex, but I was able to correct the issue by changing the line include(ABSPATH . "wp-admin/import/$importer.php");
to include_once(ABSPATH . "wp-admin/import/$importer.php");.
What I don’t understand is how this works for everyone else. Is it something with my version of PHP?
