How to know which version of WordPress you are using

Some users don’t know the version of WordPress that his website is using. This information is helpful to know whether the site is updated or not. And if not, we can know what safety problems it may suffer.

Ideally, all websites using WordPress are updated to the latest version (at the time of writing this last is the 4.5.2). But unfortunately we can find many cases where this does not happen. The reasons are varied, from incompatibilities with older versions of plugins or themes, to own sloppiness administrators, who forgets to update.

In this post, I will explain how to find this information in most cases.

Knowing the version of our WordPress

This is the easiest to learn. If you have access to WordPress Desktop just you have to look at the bottom of the window, to the right. There you will find the version of WordPress you are using. “Version 4.5.2”.

Another option is to enter the desktop menu and the widget "At a glance” you can also see which version of WordPress you have installed.

Knowing WordPress version of almost any web

If you do not have access to WordPress (or the Desktop or FTP) and still want to know which version you are using, there are several alternatives that we can use but aren’t 100% effective.

If you come across a WordPress website whose manager is very concerned about safety, you may be the case that hides the version number.

Anyway, here are three ways to try to find this information.

Method 1: Access the readme.html file

Each installation of WordPress includes the readme.html file in the root directory. Unless the webmaster have removed or concealed, if we access it using the address bar we can see the active version of WordPress.

We just write the domain name and add /readme.html in url. If we are lucky we will see the version and some texts that describe the installation process.

Unfortunately, most decent hosting providers hide default, this file (as in our case). I encourage you to try this with your web. If you see the readme.html file, it acts accordingly to avoid problems.

Method 2: Check the tag generator

WordPress adds a default meta tag in the source code of the websites with the generator name. This metatag indicates the version of WordPress in its content.

To get it, just we have to enter the site in question we want to explore and see its source code. To access the source code, we can do it in different ways, depending on the browser used. For example, from Google Chrome you just add view-source: before the web address in the address bar.

Or in Google Chrome you can access from the menu View> Developer> View Source. If you look up the word generator may find the meta tag whose content indicates the version of WordPress.

Method 3: Inspect the login window

Finally, another option is to view the source code, but this time on the login screen. Although can be changed for security reasons, this screen is accessible adding /wp-login.php to the domain name of the web we want to explore.

Once on this page (no need to have the user name and password to enter the desktop) access the source code from the browser (as I explained before) and there have to search the text see =. When JavaScripts or CSS styles are loaded in that window, WordPress adds the version as shown in the following screen (you can see the text see = 4.5.2):

Final summary

Knowing the version of WordPress that a particular website is using, is something not too difficult. We have seen different methods to get this information, which can be used against us if we use an old version of WordPress with security flaws.

I hope this has been helpful information and to try with your web the three methods described to act accordingly. And above all, do not forget to have your WordPress always update!
