Warnings in some Windows server from WPML-CMS-NAV and Sticky-Links

Resolved

Reported for: WPML Multilingual CMS 3.3.3

Resolved in: 3.3.4

Overview of the issue

In some Windows server environments, WPML-CMS-NAV and Sticky-Links may throw some warnings.

A warning like this could be shown in some WAMP stacks (Windows + Apache + MySQL + PHP):

Warning: Invalid argument supplied for foreach() in /var/www/vhosts/mydomain.com/httpdocs/wp-content/plugins/wpml-cms-nav/embedded/wpml/commons/src/wpml-auto-loader.php on line 155

Workaround

This issue will be removed on the next update of both affected plugins.

Meanwhile there are two possible workarounds: both will provide the same result.

Please note that what follows only applies to WPML-CMS-NAV and Sticky Links: don’t use this on other plugins.

  • Option one:
    1. Edit the `plugin.php` file of both WPML-CMS-NAV and Sticky Links
    2. Remove lines from 17 to 19. E.g.: 
      require_once 'embedded/wpml/commons/autoloader.php';
$wpml_auto_loader_instance = WPML_Auto_Loader::get_instance();
$wpml_auto_loader_instance->register( WPML_STICKY_LINKS_PATH . '/' );
    3. Save
  • Option two: add a subfolder called “classes” to the root of both WPML-CMS-NAV and Sticky Links plugin folders

  1. Hy!

    I have only sitepress-multilingual-cms/sitepress.php file that contains that 3 lines. I removed them and Saved.

    Than I tried to turn ON the WPML Multilingual CMS plugin, but Fatal error occurred:

    Fatal error: Class ‘WPML_WPDB_User’ not found in /chroot/home/tamaspal/tamaspalfalvi.com/html/wp-content/plugins/sitepress-multilingual-cms/inc/wpml-post-comments.class.php on line 3

    • Laki, as explained in this errata, this workaround only applies to WPML-CMS-NAV and Sticky Links.

      Please use the beta version in a non production site, to check that the issue is fixed.

      We are closing our QA now. As soon as it’s done, we will take out WPML 3.3.4 from the beta.

    • Hi Tomas,

      Please report the issue in our forum, where we can ask you more details we can’t ask here.

      Also, you may want to give the beta version a try, as long as you can test it in a non production site.
