I'm using Wordpress 3.3.1, installed on my local machine. I've gotten everything up and running, and I'm able to add posts and pages through the admin interface, but whenever I try to click the "preview changes" button from either one of my posts or pages, I get a 404 Not Found page instead. The URL appears to be correct, I've even tried copying the permalink and pasting it into the address bar, but it still gives me a 404 page. As far as I can tell the posts and pages are being added correctly, and I can view and edit their contents from the admin interface, just not from the main site itself. What could be causing this and how do I fix it?
What you have (probably) is an error with your
In most local host you can enable Permalinks support.. (its called a rewrite module)
Here is the option on my localhost (using WAMP)
Ok, I figured it out. I had a friend install this for me, and he told me that he didn't modify anything and it was a fresh install, but when I took a look at the Settings -> Permalinks screen I saw that there was a custom structure defined "/%categories%/", so I set it back to "default" and now it's working again.
