My WordPress installation couldn’t download the necessary update files fast enough. I could see that in
wp-content/tmp the .tmp-files were created and growing, but they all stopped early and WordPress tried downloading again and again. Of course, your WordPress-installation might use a different tempdir. If you’re unsure, just add the following line to your wp-config.php to make sure that the tempdir is exactly what you expect:
define('WP_TEMP_DIR', ABSPATH . 'wp-content/tmp');
Here’s what you have to do:
- Download the update manually and upload it to the server into the directory
- Modify the file
wp-admin/includes/file.phpby adding these five lines to the
function download_url, right before the line with the call to
$parts = parse_url($url); if ( empty($dir) ) $dir = get_temp_dir(); if (file_exists($dir . $parts['path'])) return $dir . $parts['path'];
- Run the „Automatic Update“ from your dashboard.
Please keep these things in mind:
- The file that you stored into the
wp-content/tmpwill be deleted after the upgrade.
- The changes to file.php will disappear as the upgrade normally overwrites file.php
How does this work?
We extract the filename from the URL that WordPress is trying to download (
$parts['path'] is the filename). If the file resides in the tempdir, simply return with this filename rather than with a temporary filename.
