How do I find out what version of WordPress is run

问题:

I have just taken over someone's hosted WordPress site. How do I find out what version he is running?

回答1:

Look in wp-includes/version.php

/**
 * The WordPress version string
 *
 * @global string $wp_version
 */
$wp_version = '2.8.4';

回答2:

Unless he edited some code to delete this, you should be able to view source on the site and look for this meta tag:

<meta name="generator" content="WordPress 2.7.1" /> 

That will give you the version.

回答3:

On the Admin Panel Dashboard, you can find a box called "Right Now". There you can see the version of the WordPress installation. I have seen this result in WordPress 3.2.1. You can also see this in version 3.7.1

UPDATE:

In WP Version 3.8.3

In WP Version 3.9.1 Admin Side, You can see the version by clicking the WP logo which is located at the left-top position.

You can use yoursitename/readme.html

In the WordPress Admin Footer at the Right side, you will see the version info(Version 3.9.1).

You can get the WordPress version using the following code:

<?php bloginfo('version'); ?>

The below file is having all version details

wp-includes/version.php   

Update for WP 4.1.5

In WP 4.1.5, If it was the latest WP version in the footer right part, it will show the version as it is. If not, it will show the latest WP version with the link to update.

Check the below screenshot.

For any wordpress site, you can go to http://example.com/feed and check the following tag in the xml file to see the version number:

<generator>http://wordpress.org/?v=3.7</generator>

Here, 3.7 is the version installed.

回答5:

Every WP install has a readme.html file.

So just type www.yourdomain.com/readme.html

回答6:

The easiest way would be to see the readme file that ships with every WordPress version itself.

http://example.com/readme.html

回答7:

If you came here to find out about how to check WordPress version programmatically, then you can do it with the following code.

// Get the WP Version global.
global $wp_version;

// Now use $wp_version which will return a string value.
echo '<pre>' . var_dump( $wp_version ) . '</pre>';
// Output: string '4.6.1' (length=5)

Cheers!

On the Admin panel in the footer you should see the words "Wordpress x.x" where x.x is your version number :)

Alternatively you can echo out the WP_VERSION constant in your script, it's up to you. The former is a lot quicker and easier.

Because I can not comment to @Michelle 's answer, I post my trick here.

Instead of checking version on meta tag that usually is removed by customized theme.

Check the rss feed by append /feed to almost of any link from that site, then search for some keywords (wordpress, generator), you will have better chance.

<lastBuildDate>Fri, 29 May 2015 10:08:40 +0000</lastBuildDate>
<sy:updatePeriod>hourly</sy:updatePeriod>
<sy:updateFrequency>1</sy:updateFrequency>
<generator>http://wordpress.org/?v=4.2.2</generator>

回答10:

can find in Dashboard At a Glance box

if that box is hidden - click on screen options at top-right corner and check on At a Glance

回答11:

Open the blog, Check source once the blog is open. It should have a meta tag like:

<meta name="generator" content="WordPress 2.8.4" />

回答12:

Just go to follow link domain.com/wp-admin/about.php

回答13:

From experience with WordPress 3.8.3:

(1) Login as admin (2) Click on the W menu in the upper left corner (3) Click on menu item "About WordPress".

This will take you to .../wp-admin/about.php

There it will say "Welcome to WordPress 3.8.3"

回答14:

Yet another way to find the WordPress version is using WP-CLI: Command line interface for WordPress:

wp core version

回答15:

I know I'm super late regarding this topic but there's this easy to use library where you can easily get the version numbers of Worpress, PHP, Apache, and MySQL, all-in-one.

It is called the Wordpress Environment (W18T) library

<?php
include_once 'W18T.class.php';
$environment = new W18T();
echo $environment;
?>

Output

{
    "platform": {
        "name": "WordPress",
        "version": "4.9.1"
    },
    "interpreter": {
        "name": "PHP",
        "version": "7.2.0"
    },
    "web_server": {
        "name": "Apache",
        "version": "2.4.16"
    },
    "database_server": {
        "name": "MySQL",
        "version": "5.7.20"
    },
    "operating_system": {
        "name": "Darwin",
        "version": "17.0.0"
    }
}

I hope it helps.
