Category Redirection and 404 Problem

Does no one know?

I’ve tried everything these past 2 days.

Have you tried:

– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the Twenty Ten theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

– resetting your custom permalinks back to the default setting. If this works, then review Using_Permalinks before setting a custom permalink structure back up again.

Yes. Now I have ??

Resetting the permalinks back to normal fixes it. I already knew that. But that doesn’t really solve the problem. When the URLs go back to normal the problem comes back.

It’s an issue with how wordpress sees these URLS and directs the page.

Even updating or using advanced permalinks hasn’t solved the issue.

Quoting from the codex: using permalinks:

For performance reasons, it is not a good idea to start your permalink structure with the category, tag, author, or postname fields. The reason is that these are text fields, and using them at the beginning of your permalink structure it takes more time for WordPress to distinguish your Post URLs from Page URLs (which always use the text “page slug” as the URL), and to compensate, WordPress stores a lot of extra information in its database (so much that sites with lots of Pages have experienced difficulties). So, it is best for the first structure tag to be a numeric one, such as /%year%/%postname%/.

Perhaps the problem you are experiencing is due to starting with a non-numeric permalink.

Nope, doesn’t seem to solve it.

Check with your hosts that mod_rewrite is running on your server.
