Support » Fixing WordPress » Edit Permalink Structure problems

  • Hi,

    I’ve been trying to use the Edit Permalink Structure page under options to create a different structure for my permalinks. However, when I put any of the suggested structures it breaks all the navigation links (archives, catagories) on my site. It also breaks the links to the RSS feed. I’m using WordPress 1.5. I tried the method where you need to add things to your htaccess file and the one where you don’t but neither work. Can anyone help me?

    My blog is at

    The links are working right not because I don’t have the custom permalink structure turned on.

  • Are you sure mod_rewrite is enabled on your server? Here’s a simple .htaccess you can use to test it:

    Options +FollowSymLinks
    RewriteEngine on
    RewriteRule ^home/$ /index.php [L]

    With this, if home/ goes to index.php, it’s working. If not, contact your provider to see if they allow it/can turn it on, etc.

    I have the same problem, and I use htaccess in several other domains of my server.

    when activated links break about 50% of the time

    If it’s an off and on issue, see this post for one possible fix (originally for another issue, but you never know which problems are related):

    The problem isn’t an off and on issue and mod_rewrite is enabled because I have other rewrite rules that work. Also, I’ve tried setting it up using the method that doesn’t require mod_rewrite and that doesn’t work either. I haven’t the foggiest what I am doing wrong.

    Are there issues depending on where WordPress is located on the server?

    Boy, I’m right there with you. This has been driving me crazy all morning. I’m also trying to get the permalink structure set, this is my goal:


    However, I run into the same 404 issue as described. Trying to troubleshoot a bit, I have been successful with the following:


    Just the permalink.


    Where I set the category name manually.


    Two directories generated, including using post_id instead of postname.

    In these situations, I am able to go directly to a link without the 404. All hell breaks loose when I invoke the /%category%/ variable, is there somethink I am missing here?

    The saga continues. As a follow-up, I’m also unable to get %author% to work.


    Returns the following URL:

    Obivously, 404 material. For some reason, the variable isn’t getting placed here.

    Just found the answer to the category issue…


    After initial attempts at getting the Ungreedy plugin to work, I took a look at the php code, trying to figure out what the script actually did. Here’s the fix, your htaccess file must be edited manually.

    When using the %category% tag in your permalink manager, here’s how the htaccess file is written… the last nine lines look something like this:

    RewriteRule ^(.+)/page/?([0-9]{1,})/?$ /index.php?category_name=$1&paged=$2 [QSA,L]

    What you need to do is replace that first (.+) with ([_0-9a-z-]+), so that each line looks similar to this:

    RewriteRule ^([_0-9a-z-]+)/page/?([0-9]{1,})/?$ /index.php?category_name=$1&paged=$2 [QSA,L]

    Once I did this, I was able to eliminate the 404s. Credit this post for the help:

    Okay I’m really frustrated now. I can’t seem to make this work correctly. I’ve even tried the following permalink structure

    This is supposed to work regardless of if mod_write is installed.

    From what I can tell my site is on a server running Apache 2.0.46

    Does anyone have other suggestions?

    Thinkeric, thanks … your fix work for me.

    Well, not exactly 🙁 As soon as I write another post and save it, WP re-writes .htaccess back to the original.

    The manual .htaccess modification mentioned by thinkeric is the only thing that has been able to solve my /%category%/%postname%/ problem as well. Yet, as mahadewa says, every time I do anything significant with WP, .htaccess reverts to broken mode.

    Is there any way to make this .htaccess modification permanent (or at least persistently update those 9 lines), through a plugin or hacking part of WP that writes to .htaccess?

    If that sounds like a rhetorical question with a simple (but nonetheless disappointing answer — “not yet!”), it’s meant to be. But seriously, WP’s future as a legitimate CMS depends on this sort of functionality.

    is just never workt

    Hi folks, I’m new here. Thinkeric’s solution worked for me, and I wanted to make it permanent. The code that writes these rules for .htaccess is in /wp-includes/classes.php. Look for ‘class WP_Rewrite’, and the definitions start from there. There’s four arrays defined before the first function. You should be most concerned with ‘$rewritereplace’. This corresponds directly to ‘$rewritecode’ above it. In my install (; I’m not sure if it’s different for 1.5.0 or 1.5.1), category is the 9th item in the array. I changed that from ‘(.+?)’ to ‘([^/]+)’ and it works fine now…

    …except for one thing. On the indiviual post pages, the text of the post isn’t showing up. I think it has something to do with the_content() reading the URL, I’m not sure.

    … except this breaks sub-categories. Sorry about that.
