Minimum Requirements
In order to run, WPML requires the following:
- WordPress 3.0 or later
- PHP 5.2.4 and above with memory limit of at least 64Mb (see WP memory settings).
- MySQL 5.0.5 and above.
- That you can create tables in your database.
Our development platform is Ubuntu 10.10. WPML runs fine on any other Linux distribution, but this is where we’re getting the minimum requirements from.
It may run on earlier versions of PHP an MySQL, but we can’t test that. If you’re using earlier versions, we strongly recommend enabling WPML’s debug mode. This will surface any PHP errors and let you know if things don’t run as they should.
Feel free to comment here about using WPML with other versions.
How to check which version of PHP you’re actually using
Some shared hosting companies have installed both PHP4 and PHP5. The best way to check which version you’re actually using is to ask the PHP processor itself (not the technician in the hosting company).
Create a file called php_info.php and put it in your WordPress directory (just next to wp-config.php). This file should contain the following:
<?php phpinfo(); ?>
Not a big deal, right? If you need to, you’re welcome to download it as a ZIP file. Grab php_info.zip (of course, you’ll need to unzip it before uploading to your server).
Once there, open a browser and go to: http://yourdomain.com/php_info.php
You should see something like this:

php-info.php showing PHP5
On top, it says which version of PHP you’re running. If it says PHP Version 4, it’s not going to fly. The best thing to do is email your hosting company and ask them how to enable PHP5.
Permalink structure
WPML adds language information to URLs. It’s been tested with the following permalink structures:
- The default
- /%year%/%monthnum%/%postname%/
Explanation:
Other permalink structures may work too, but can cause problems on different configurations. In all our sites, we’re using /%year%/%monthnum%/%postname%/.
For pages, you’ll get the exact same URLs as with /%postname%/. However, with this permalink structure, there’s no way WordPress will confuse between pages and posts, triggering potential problems for language resolution.
My server runs PHP version 5.2.17. Anyone had any experience with running wpml on this?
It should. If you have any sort of trouble, we’ll refund your purchase immediately.
Does it work with WP multisite?
Yes, WPML works fine on Multisite installs, both on child sites and on the main site.
I am trying to find out if WPML is working with the Adventure Journal theme, do you know??
Adventure Journal info:
http://www.contextureintl.com/wordpress/adventure-journal-wordpress-theme/
Sorry, we haven’t tested with that theme. You can buy WPML and if there’s any problem, get a full refund.
Can I test it with the free version? Or would that not be conclusive?
WPML doesn’t have a free version, but we do have a full-refunds policy. If you buy it and you’re not happy, for whatever reason, we return your money immediately.
Hi! I have upgrade my wordpress to 3.3.1, Will WPML work?
Yes. WPML runs fine with WP 3.3.1. I’m updating it on our site to indicate the correct version number.
To mario ,
Will this affect the SEO any bit?
hello i just found your plugin that seems very robust and woud speed up turning wordpress in to a multilingual cms.
I need to ask you if it is as easy with the “twentyeleven” theme (native to the WP platform) as i saw in your presentation vid.
I ask you this because the theme developed for my CMS site started on the “twentyeleven”.
Thankx im advance
Yes. WPML runs fine with TwentyEleven.
To Dr. John Pollard,
It means that when using either the default permalink structure OR this one:
/%year%/%monthnum%/%postname%/
The pages will have the same URL as if you had set the permalink to just:
/%postname%/
But the posts will use the permalink suggested here i.e.:
/%year%/%monthnum%/%postname%/
So that WP don’t confuse posts and pages and thus, you don’t have any bugs in your WP site with WPML.
