Network/Upgrade issue with WordPress 3.3.3 load

From … 3.3.3? We’re on 3.4.1 now. Usually that error happens due to a theme or plugin on the site where it failed.

Im going from 3.2.1 to 3.3.3. I checked my server settings to make sure the allow fopen is on and it was… I can upgrade and update the database by going out to the site’s wp-admin and adding upgrade.php to the URL. But when I try to click the network upgrade I get the error I mentioned above.

So I am assuming it is not a theme or plugin issue, because it allows me to upgrade and update the site that it claims is causing the error…

And a side-note when I click on the URL in the error message, the wp-admin/upgrade.php?step-upgrade_db. I get a page that displays a “0”. I looked into wp-admin/upgrade.php and found this code:

delete_site_transient('update_core');

if ( isset( $_GET['step'] ) )
	$step = $_GET['step'];
else
	$step = 0;

// Do it.  No output.
if ( 'upgrade_db' === $step ) {
	wp_upgrade();
	die( '0' );
}

$step = (int) $step;

$php_version    = phpversion();
$mysql_version  = $wpdb->db_version();
$php_compat     = version_compare( $php_version, $required_php_version, '>=' );
if ( file_exists( WP_CONTENT_DIR . '/db.php' ) && empty( $wpdb->is_mysql ) )
	$mysql_compat = true;
else
	$mysql_compat = version_compare( $mysql_version, $required_mysql_version, '>=' );

Why would $step = 0? How can I make it not equal 0?

So I am assuming it is not a theme or plugin issue, because it allows me to upgrade and update the site that it claims is causing the error…

Understandable assumption ?? But. Did you know that all plugins and themes on your main site impact the updater? And that any plugins or themes on a subsite will impact when that site is being updated?

This is a case where you can either keep doing it by hand and hope it goes away when you make the next upgrade, or disable your plugins and try again.

Hi, I have the exact problem when upgrade my site from 3.4.2 to 3.5, I disabled all plugins but still got

Your server may not be able to connect to sites running on it. Error message: Could not open handle for fopen() to https://my_url/wordpress/my_site/wp-admin/upgrade.php?step=upgrade_db

I can upgrade the site using https://my_url/wordpress/my_site/wp-admin/upgrade.php

Is it a bug or other problem?

Thanks!

fredlim – Please make your own topic.

You can use /upgrade.php though.
