Problem: If you're experiencing a fatal error when trying to edit translations in the custom post type 'Nemovitost', and the error message indicates an issue with
array_walk()
expecting an array but receiving a string, the problem might not be directly related to WPML. Solution: We recommend enabling gzcompression on your server. This adjustment has resolved similar issues by ensuring that data handling processes are optimized for performance. After enabling gzcompression, you can safely remove any temporary fixes that were applied. Additionally, keep an eye out for future WPML updates, as they will include a built-in warning to alert you if gzcompression is disabled again.
If this solution does not resolve your issue, or if it seems irrelevant due to being outdated or not applicable to your case, please visit our support forum to open a new support ticket. We also 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.
