I'm using WordPress 3.1.3 as a full CMS, installed in the root directory of a domain. I have it setup using the built in options to have a static page as the home page, and then my blog at http://www.example.com/blog.

What I would like is to have my single blog posts, category pages, archive pages, and tag pages, and any other blog-related pages have the "prefix" of /blog/ in their link structure. So a post URL would be www.example.com/blog/post-title

Right now, I only have the category pages working correctly. This was accomplished by adding the following line to my .htacces file:

RewriteRule ^category/(.+)$ http://www.example.com/$1 [R=301,L]

Then, I set the Category Base to "blog" on the Permalinks Settings page in WordPress. This gives category pages the URL of: www.example.com/blog/category-name (without removing the category prefix in .htaccess, they had the URL category/blog/category-name).

In an attempt to get this working for the other things I want it to work for, I set my Tag Base to "blog." I also made my Custom Permalink Structure: /blog/%postname% (as suggested by a few threads I've found searching on Google).

These settings give the URLs for the single blog posts, tags pages, and archive pages the URL structure I'm looking for. However, it makes them all lead to 404 errors.

I deleted my .htaccess file to ensure WordPress was writing to it, and it is. If I remove the /blog/ from the permalink structure, everything works correctly, but I no longer have the URL structure I'm looking for.

I'm at a loss as to what I should do. I keep reading threads and guides saying this is as simple as adding /blog/ to the permalink structure, but so far it hasn't been nearly that simple.

.htaccess contents:

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

  • As a side note, the permalink shown while editing a post is "wrong". It won't show the final link.

Go to Settings>Permalinks and add it to the permalink structures

    That was one of the first things I tried, and was resulting in 404 errors. So I had it disabled for a few hours, and decided to try it again after reading your response. It's now working for my single post pages. I also got the category pages working again. That just leaves the tag pages and the archive pages that need the /blog/ in them.

  • If you look at the page there is a spot for the tags as well. As for the archive pages are you talking about the the page that shows the list of articles, tags, categories, etc. or archived posts

  • With the tags, if I add blog into the Tag Base area it gives me the correct URL structure "mydomain.com/blog/tag-name" but that page then gives me a 404 error. With the archives, I mean the page that shows the archived posts for a particular month. I would like the URL to be mydomain.com/blog/2011/05. That URL structure shows up when I click an archive link, but also gives a 404 error. And now I'm getting 404 errors for the single blog posts again. Could this be a plugin that's causing problems?

  • Is your .htaccess setup right?

  • I believe so, Wordpress adds in the rewrite rules any time I change them. Should there be anything in particular in there for something like this?

You get 404 errors when you add /blog/ to the custom permalink structure and then also add /blog/ to the category base. It should only be added to one, the custom permalink structure.

If you leave your category base and tag base blank and just add /blog/ to the front of the custom permalink structure to make it look like this /blog/%postname% - this will get the desired result.

Your pages will look like this: domain.example/pagename/ Your post URL will look like this: domain.example/blog/postname Your category URL will look like this - domain.example/blog/category/postname

    Good catch on adding to only one section. This solution also will add /blog/ to the category and archive pages which is good. This should really be the accepted answer.

  • I'm glad this method also applies to URL for the categories page.

    it will attach the prefix to ALL your custom post types

    A usual question here would probably be: How do you manage this for just "post" post types and how do you translate /blog for example for different languages? :)
