Problem: After changing the language URL format to use subdirectories, translated custom post-type posts are not appearing on the site. Solution: We recommend checking the status of your translated posts in the WordPress admin area. For instance, go to the edit page of the problematic post and ensure that the status is correctly selected. This can often resolve issues with posts not appearing after a URL format change.
If this solution does not resolve your issue or seems irrelevant due to being outdated or not applicable to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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.
