Workaround

Our development team has fixed the issue and the fix will be shipped with the upcoming WPML release.

In the meantime, you can use the following workaround to fix the issue on your site:

1. Backup your WordPress site files and database.


2. Using FTP, navigate to wp-content/plugins/sitepress-multilingual-cms/classes/url-handling/converter/strategy/class-wpml-url-converter-subdir-strategy.php


3. Replace this code snippet:

   private function get_language_of_current_dir( $language_code, $value_if_default_language = null ) {
   		if ( ! $this->use_directory_for_default_lang && $language_code === $this->default_language ) {
   			return $value_if_default_language;
   		}
   
   		return $language_code;
   	}

   with:

   private function get_language_of_current_dir( $language_code, $value_if_default_language = null ) {
   		/** @var SitePress $sitepress */
   		global $sitepress;
   		$defaultLang = $sitepress->get_default_language();
   
   		if ( ! $this->use_directory_for_default_lang && $language_code === $defaultLang ) {
   			return $value_if_default_language;
   		}
   
   		return $language_code;
   	}
