Call to undefined function wp_get_upload_dir()

Resolved

Reported for: WPML Multilingual CMS 3.6.3

Resolved in: 3.7.0

Overview of the issue

When you update to WPML 3.6.x you might encounter the following error:

PHP Fatal error:  Call to undefined function wp_get_upload_dir() in /public_html/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-templates.php on line 316

This error is caused when using an old version of WordPress. The function wp_get_upload_dir() was introduced in WordPress 4.5 version as you can read here

Workaround

This issue will be fixed in the upcoming version of WPML.

As a workaround, use the following steps:

  1. Edit the class-wpml-ls-templates.php file in the ../wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/ folder.
  2. On line 316, replace:
    $uploads = wp_get_upload_dir();
    with
    $uploads = wp_upload_dir( null, false );

    • Hello, Pierre
      You seem to be having quite an old version of WPML.
      Please note that the current release is WPML 3.6.3, and you are using WPML 3.1.4.
      It is recommended that yo use the latest version of WPML with WordPress 4.7.2 as version 3.1.4 is too old and may not be entirely compatible with all of the changes introduced in WordPress.

      • WPML will never got you “a virus or something” if it was downloaded either from our installer or from this site.
        I already responded to you on a way to fix the problems in my reply from before.

      • Hello,

        I updated the plugin and I have the same problem: Fatal error: Call to undefined function wp_get_upload_dir() in /htdocs/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-templates.php on line 316

        My WordPress version is 4.0.16.

        I tried via FTP but the thing is that ../sitepress-multilingual-cms/.. folder is missing.

        How to proceed to get this solved??

        Thank you

        • Hello enrique,
          If you are getting that error, then you should follow the path in the error – /htdocs/wp-content/plugins/sitepress-multilingual-cms/classes/language-switcher/class-wpml-ls-templates.php
          Perhpas you are looking in the incorrect directory for the plugin.
