Sync Post Translations

This thread is resolved. Here is a description of the problem and solution.

Problem:
If you're experiencing an error with

sync_with_translations()

plugins/sitepress-multilingual-cms/inc/post-translation/wpml-post-synchronization.class.php:321

, it might be due to a conflict or a specific issue within your WPML setup.
Solution:
We recommend trying the following steps to potentially resolve the issue:
1. Navigate to WPML → Support → Troubleshooting.
2. Run these options:
- Clear the cache in WPML
- Remove ghost entries from the translation tables
- Fix element_type collation
- Fix WPML tables collation
- Set language information
- Fix post type assignment for translations
Additionally, if disabling all other plugins except WPML resolves the issue, this indicates a possible plugin conflict. In such cases, re-enable the plugins one by one to identify the conflicting plugin.

If these steps do not resolve your issue or if it is unrelated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the problem persists, please open a new support ticket so we can assist you further.
