WPML Multilingual CMS 4.9.3

WPML 4.9.3 brings a wide range of fixes and improvements — from site migration and string translation to performance, admin usability, and editor compatibility.

Features

• New filter hook for developers to return translated user meta values
  WPML now intercepts calls to get_user_meta() and returns the translated value for the current language. This is useful when displaying user profile fields (e.g. job title, bio) on multilingual sites. To enable this behaviour, add the following to your theme or plugin:

  add_filter( 'wpml_translate_get_user_meta', '__return_true' );

• New filter hook to globally disable all WPML email notifications
  WPML sends automatic emails from several internal components (translation job assignments, overdue job reports, batch summaries, etc.). Previously there was no official way to suppress them — developers had to rely on workarounds inspecting the call stack. This new hook provides a single, supported way to disable all WPML emails at once:

  add_filter( 'wpml_send_email_notification', '__return_false' );

  Or selectively, based on email type and recipient:

  add_filter( 'wpml_send_email_notification', function( $send, $email_type, $recipient ) {
      if ( $email_type === 'overdue_jobs_report' ) {
          return false;
      }
      return $send;
  }, 10, 3 );

  This is particularly useful on staging or development environments where you want to prevent emails from reaching real users.

Improvements

Migration and Setup

• Safer and More Reliable Migration Process
  WPML now makes it safer and easier to move or copy a site from one domain to another. If something goes wrong during the migration, the wizard stays visible so users can retry, with clearer messages, better logging, and guidance on where to find the migration code. WPML also automatically fixes misconfigured alias domains, removes the unsafe “Move” option, and improves performance for sites using the Classic Translation Editor.
• Added a new option to reset the WPML Setup Wizard when it gets into a corrupted state.
• WPML now notifies the translation service when a site key is unregistered.

Performance

• Reduced redundant language filtering calls on sites with many ACF fields for better performance.
• Removed outdated WP Super Cache integration code that was no longer needed.

Admin and User Experience

• Unlocked WPML settings are now visually indicated in the admin interface.
• String Translation dashboard filters now show labels and default to Frontend strings.
• Clarified how Media Translation settings affect images and featured images.
• The notification about jobs that cannot be finished now links directly to the Translation Dashboard.

Fixes

• Some posts containing Base64-encoded data were not being sent for translation
  In a previous release, we started blocking some posts because they contained Base64-encoded data, to prevent issues during the translation process. However, this also blocked some posts that could actually be translated, or where the Base64 content could simply be ignored. We’ve updated how WPML handles Base64-encoded content — posts that can be safely translated are no longer blocked. A more precise validation approach is planned for an upcoming release.
