capabilities.php and require_once('pluggable.php');

  • Many WordPress updates ago (I forget how long), we upgraded to the latest version. But after the upgrade, both the backend and front end appeared blank. No errors,just no content.

    After much searching around, I found a post that suggested adding:
    require_once(‘pluggable.php’);
    to the top of wp-includes > capabilities.php

    that fixed the problem.

    Well, great, except that now everytime we update WordPress, we have to perform the same modification on capabilities.php, because it seems that file is overwritten in each update.

    What’s happening here? Clearly there’s something wrong and while this is an easy fix, it’s a hassle, especially when WP does an auto update and we end up with a blank site for a while.

    It’s more than likely a plugin or theme function conflict, but in order to fix it, you need to first identify which one is at fault.

    Try manually resetting your plugins (no Dashboard access required). If that resolves the issue, reactivate each one individually until you find the cause.

    If that does not resolve the issue, access your server via FTP or SFTP, navigate to /wp-content/themes/ and rename the directory of your currently active theme. This will force the default theme to activate and hopefully rule-out a theme-specific issue (theme functions can interfere like plugins).
