Problem:
If you're experiencing PHP errors with the 'sitepress-multilingual-cms' WordPress plugin using PHP 8.2, specifically a deprecated rtrim() issue, you are not alone.
Solution:
We recommend updating to WPML version 4.6.12, which includes a fix for this issue. This version is currently released.

If this solution becomes outdated or does not apply to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent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. If the issue persists, please open a new support ticket.
