[Resolved] Re-creating posts that existed previously causes 404 when new page is published

Problem:
The client is experiencing 404 errors when trying to recreate trashed pages with identical names and permalinks on a site using WPML. The issue does not occur when WPML is deactivated, and it does not appear on a staging site.
Solution:
We identified that the problem might be related to caching mechanisms used by WPEngine plugins on the live site. Clearing the cache resolved the issue, allowing pages to be recreated without returning a 404 error. If you're experiencing this issue, we recommend trying to clear your site's cache. Additionally, ensure that any caching plugins or systems, particularly those related to object caching, are properly configured or temporarily disabled when making such changes.

Please note that this solution might be outdated or not applicable to your specific case. If the problem persists, 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 necessary, do not hesitate to open a new support ticket at WPML support forum for further assistance.
