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: 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?

        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 just buy Multilangual CMS for use on WordPress version 3.1.4 and I have a problem to make it work.

    1 – When I use the last version (Version 2.4.2) I get the following message:
    ——————————————–
    WPML notice: Upgrades to this version are only supported from versions 1.7.0 and above. To upgrade from version 1.0.4, first, download 2.0.4, do the DB upgrade and then go to this version.
    ——————————————–

    2 – When I use the last version (Version 2.0.4) I get the following message:
    ——————————————–
    L’extension n’a pu être activée, car elle a déclenché une erreur fatale.

    Il y a une nouvelle version de WPML Multilingual CMS disponible. Afficher les détails de la version 2.0.4.1 ou lancer la mise à jour automatique.
    ——————————————–

    3 – When I update with the Version 2.0.4.1 I get the following message:
    ——————————————–
    L’extension n’a pu être activée, car elle a déclenché une erreur fatale.
    ——————————————–

    Finally I do not know how to do. Is there any thing I’m doing wrong?
    Can you assist me with a solution?

    Thank you in advance.

    Paul

      Can you please post about this in our technical forum? Explain which version of WPML you’re upgrading from.

      You are reporting fatal errors. It would help, a lot, if we can know what these errors are. You can see PHP errors by enabling PHP error log file. See this for instructions:

    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.
