WordPress update to 4.5.2 failing

look in /wp-includes/version.php

That will show you what version you have. It’s possible that the site was upgraded but a cookie or something makes it think it’s not updated.

Here is what is in the file:
<?php
/**
* The WordPress version string
*
* @global string $wp_version
*/
$wp_version = ‘4.5.1’;

/**
* Holds the WordPress DB revision, increments when changes are made to the WordPress DB schema.
*
* @global int $wp_db_version
*/
$wp_db_version = 36686;

/**
* Holds the TinyMCE version
*
* @global string $tinymce_version
*/
$tinymce_version = ‘4310-20160418’;

/**
* Holds the required PHP version
*
* @global string $required_php_version
*/
$required_php_version = ‘5.2.4’;

/**
* Holds the required MySQL version
*
* @global string $required_mysql_version
*/
$required_mysql_version = ‘5.0’;

OK. That means you still need to update. That should be an automatic update. Maybe if you wait it will update itself. Automatic updates are security patches.

So very interesting. I just went to click the UPDATE NOW button and it worked:-) If failed 10 times before finally going. Doesn’t really make any sense.

Glad to hear it finally worked.
