I just installed the 2.3.1 version of WP to a subdomain. I can log in just fine and it takes me to my dashboard. However, if I click on the dashboard link from anywhere else in the admin area menu, it sends me to a non existent page. This problem is only with the dashboard link and I haven't modified anything or even installed any plugins.
Here's an example of what is happening:
When I hover over the menu link, my browser's view bar says
But when I actually click on the link, it redirects me to
Note the addition of "www" and of my subdomain folder "blog".
At first I thought might be a mod_rewrite problem, but I don't have an .htaccess file in my subdomain root and my domain root .htaccess file doesn't have anything in it that would affect this. My guess is that it's got something to do with the index.php page itself, but I couldn't find anything in the code.
Any ideas? Is anyone else with WP installed in a subdomain having this problem?
In case you're wondering my wordpress address and blog address are both set to http://blog.mydomain.com which is the correct setting.
