Problem:
You are trying to offer event registration in both English and French with Event Tickets Plus and WPML, using a workaround to display ticket blocks on translated event pages. However, the add tickets function does not work for events that have been translated, and toggling the language affects the header and footer language as well.
Solution:
Firstly, it's important to note that Event Tickets Plus is not officially compatible with WPML. To display tickets on translated events, you need to manually add the ticket to each translated event. This issue has been reported by other users and is known to the Event Tickets team. For more details, you can check this forum thread: Event Tickets Plus Integration with WPML.

For the issue of language toggling affecting the entire page, you attempted a workaround by modifying a specific query to only show English tickets on the French page. Here is the code snippet you used:

add_action('pre_get_posts', 'maybe_force_english_tickets');<br />function maybe_force_english_tickets($query) {<br />  if (!is_admin() && isset($query->query['meta_query']['_tribe_wooticket_for_event_in'])) {<br />    do_action('wpml_switch_language', "en");<br />  }<br />}

However, this requires custom coding, which is beyond our support scope. If you need further customization, consider hiring a professional from WPML Contractors.

Please note that this solution might be outdated or not applicable to your specific case. We highly recommend checking related known issues at WPML Known Issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket.
