Problem:
I read quite some threads about this topics already, but I am still not sure what is the best option to use in my situation, could you help me?

Some basics:
- We have an English website with a lot of content.
- We want to translate only a part of it (e.g 30% of the pages) into Spanish
- We want to use Advanced Translation Editor
- We use Elementor page builder

So we should be able to:
1. Translate full pages from English into Spanish with the Advanced translator Editor
2. Once a page is translated, go to the Spanish page in Elementor page builder and make some modifications (e.g remove a section or links to pages that don't exist in Spanish. Since only a part of the Website is translated, some sections are linking to non existing content in Spanish and we should remove them.)
3. In the future, when the original English page is updated, we should be able to translate these modifications via the Advanced translator Editor into Spanish.

What is the best process for this?

Option 1: Translate
Option 2: Duplicate
Option 3: Duplicate and "Translate independently"
Option 4: ?

Solution:
In this case, the best alternative is to translate the content manually. Therefore, it would be Option 3: Duplicate and "Translate independently".

If you use the Translation Editor to translate the content, edit the Spanish version with Elementor to have a different design, it'll be overwritten when you make a modification in the original page, and update the translation. You can check by yourself this behavior:

- Translate a page with Advanced Translation Editor or Classic Editor

- Edit manually the translated page with Elementor

- Make a small change to the default page

- Update the translation and check that the edition you made will be overwritten with the original page layout

So, in order to avoid this and use manual translation, please follow these steps:

- Open the page/post you want to translate manually

- In the Language box, turn off WPML’s Translation Editor switch found in the ‘Translate this Document’ section

- In the 'Use the WordPress Editor to translate' pop-up dialog that appears, select 'This page' option

- In the Language box, select the Duplicate checkbox, and then click Duplicate. This will duplicate the page in the selected secondary language

- Click on the pencil icon to edit the page in the other language

- On the editing page of the duplicated page, click 'Translate independently' in the Language box

- Translate the page or edit the design

Problem:
Learndash courses disappeared from the frontend after updating to WordPress 5.8

Solution:
The debug log file showed the following error:

PHP Fatal error:  Uncaught InvalidArgumentException: element_id and type do not match for element_id:42 the database contains post_attachment while this function was called with post_post in xxxx/wp-content/plugins/sitepress-multilingual-cms/classes/core-abstract-classes/class-wpml-set-language.php:34

And it was fixed with the following steps:

Go to WPML > Support > Troubleshooting page, then click these options:

- Clear the Cache in WPML
- Remove ghost entries from the translation tables
- Fix element_type collation
- Fix WPML table collation
- Set language information

Problem:
I have migrated the website from our staging server to the live server and I get this error:

We have detected a problem with some tables in the database. Please contact WPML support to get this fixed.

Table 'himmelsg_wp991.wp0g_icl_strings' doesn't exist

Array
(
[language] => en
[context] => WP Endpoints
[gettext_context] =>
[domain_name_context_md5] => 8d0ee533eb6eaa9960c52ecb3fc80232
[name] => order-pay
[value] => order-pay
[status] => 0
[translation_priority] => optional
[allow_empty_value] =>
)

I followed the instructions here: https://wpml.org/errata/missing-_icl_strings-_icl_string_translations-data-tables/

But the issue is still there, the code made no difference. The error doesn't appear on the staging server.

Solution:
We could solve the icl_table issue in your website following these steps:

- First, we excluded WPML plugins and reinstalled with their latest versions
- Then, we removed the code on functions.php that you've added in order to recreate the icl tables
- We went to your database and could find the entries "wpml_string_table_ok_for_mo_import" and "wpml_notices"
- After we deleted them, the issue was fixed and the notice on your WP Dashboard disappeared

Problem:
In WPML - Settings - Custom Fields Translation, many fields are linked to a plugin that no longer exists, but still many Fields are present. How to remove them?

Solution:
WPML doesn't know once you remove a plugin. All fields are still active in the DB and therefore, WPML still displays them. Please refer to the following post, which explains this perfectly for ACF Custom Fields.

Relevant Documentation:
The whole process is identical for any Custom Field added by a Theme or Plugin: https://wpml.org/forums/topic/deleted-acf-fields-not-removed-from-translation-editor/#post-5576393. The only solution is to remove the entries from your _postmeta table manually.
