I have two blogs hosted on a shared plan from Dreamhost. I've upgraded both blogs to WordPress 3.0.
After upgrading, I am getting intermittent 404 error pages, but only from the admin panel. It's happening on both blogs and it was never an issue before.
For example, if I click to publish a blog post, sometimes it will publish. Other times, I will get a 404 page not found error. The same thing happens if I click on other links like Plugins or whatever from the WordPress Admin panel.
What can I do to resolve this problem?
