Hello there.
I'm getting this error upon login and logoff on my test server. (site address) refers to my actual test site IP number. Though I get this error, the site does process the logon/logoff, as if I go back a page and reload, I've been logged off/on. Another odd part of this is that the logon process works if I log off while on one of the submenus of the admin page, go back and reload in order to process the logoff, and then I can then log on to the submenu admin page without seeing the error message. (but not the primary admin menu page)
The site works perfectly other than this logging on/off issue. All administrative functions work properly, and I've installed and successfully tested and reconfigured several modules and themes.
But, when I try to log on or log off, I get the above error, which takes me to the following URL:
http:/(site address):8080/drupal-4.7.0/(site address):8080/drupal-4.7.0/
It seems to me that it is related to the double call of the address, as if it's trying to find a folder called "(site address:8080)/drupal-4.7.0/" in my drupal-4.7.0 directory and since such a folder doesn't exist, it's being denied permission.
I'm using Apache 1.3 running on port 8080, MySQL 5.x, and this is with Drupal 4.7.0 beta 5, running on Windows XP.
It is definitely not folder permissions, as I've set those to Full Control for several users (I_USR included) to test. I am using an .htaccess file, though it is the default one that came with Drupal. I have "AllowOverrides ALL" set in my httpd.conf file, and I know it works as without the .htaccess file present in the Drupal-4.7.0 folder, I cannot access the site at all.
