  • What conditions will trigger WordPress to display a 404 page other than a given URL not existing?

    I have over a dozen WordPress installs, and some of them are on DreamHost (which is starting to seem like a mistake). The ones on DreamHost—and only the ones on DreamHost—exhibit an occasional bug that I cannot understand. When using the various functions of wp-admin, such as browsing past posts, editing a comment, etc., I will periodically receive a WordPress 404 error. This is while viewing totally mundane URLs — /wp-admin/post-new.php, for instance. A reload of the page just about always resolves the problem, although sometimes a series of reloads are required to get the page to appear.

    I’ve tried to determine what conditions will trigger WordPress to display a 404, but I’ve had no luck sussing out where to find that within the code.

    My guess is that this is because of DreamHost’s chronically overloaded servers. Perhaps it’s killing off a MySQL query in progress, which causes WordPress to receive a false response as the query result, which simply displays a 404 for lack of any better response?

    I’d love to hear either a) where to find WordPress’ 404 triggers or b) what’s causing this, should somebody know.

  • I’m getting a lot of 404 errors in the admin section.
    Users : add-new.php
    Tools : Tools
    optimize-db (the plugin)

    The refresh isn’t helping me unfortunately.
    I’m on A Small Orange though, not DreamHost.
    I’m on PHP5 and WP 2.7.1

    Hi Waldo,
    I am experiencing the exact same as you, however even after reloads of the same page, cannot get past the 404.

    Did you ever find an answer to this problem?
