Compatibility

Problem:
You are using WP 6.7.1 with the Bellevue theme, Motopress Hotel Booking, and an official add-on to generate PDF invoices. You are trying to translate automatically generated invoices for bookings in additional languages (FR/NL), but some items are not being translated despite the terms being correctly translated on all website pages and in automatic generated admin e-mails.
Solution:
We suspect this might be a compatibility issue since the PDF add-on plugin is not mentioned in our internal systems. Here are the steps we recommend:
1. Confirm if the issue persists when you disable all plugins except Motopress and WPML.
2. If the issue continues, consider creating a sandbox environment to replicate the issue, or contact the Motopress team to inform them of the issue.
3. Modify the plugin code:

• Backup your site.
• Open

  .../wp-content/plugins/mphb-invoices/classes/pdf/pdf-helper.php

• At line 248, replace:

  $booking = MPHB()->getBookingRepository()->findById($booking_id);

  with:

  $booking = MPHB()->getBookingRepository()->findById($booking_id);<br />// WPML Workaround for compsupp-7849<br />if (class_exists('Sitepress')) {<br />    $booking_language = $booking->getLanguage();<br />    do_action('wpml_switch_language', $booking_language);<br />}

• At line 294, replace:

  return $render_variables;

  with:

  return $render_variables;<br />// WPML Workaround for compsupp-7849<br />if (class_exists('Sitepress')) {<br />    $default_lang = apply_filters('wpml_default_language', NULL);<br />    do_action('wpml_switch_language', $default_lang);<br />}

4. Some strings may also need to be translated in String Translation.
5. Create a French booking to see if the invoice is then in French.

Problem:
You are working on a site under development and trying to translate custom meta boxes using WPML. You have referred to the documentation but found it unhelpful as the translation of custom meta boxes is not working as expected.
Solution:
If you're experiencing issues with translating custom meta boxes in JetEngine using WPML, we recommend the following steps:
1. Create the Labels and Values for the checkbox in JetEngine > Glossary. Ensure values are in lowercase to differentiate them later in String Translation.
2. In JetEngine's Post Type settings, set the source to Glossary and select the glossary created with the values.
3. Navigate to WPML > Settings > Custom Fields Translations, find the name of the meta field, and set it to copy.
4. Go to WPML > String Translation and ensure that only the Labels are translated, keeping the values the same as the original. Setting values in lowercase helps differentiate between labels and values.
5. Make a minor change to the original post containing the value and update the translation.
This approach addresses the issue where values were being mistakenly translated instead of labels, causing JetEngine not to maintain state across translations.
