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

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If this solution does not resolve your issue, or if it seems irrelevant due to being outdated or not applicable to your case, please visit our support forum to open a new support ticket.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.

Hello,

Thank you for the information. Everything is now working for me too. In any case, I would still need the fix plugin so that I can apply everything to the production website. Please can you send it to me.

Best regards,

Hi,

I reinstalled the ICL Translate Field Data Fix plug-in on your dev site: hidden link. You can download it from there and install it on your production site. After installing and activating this plugin, you can see its options in Tools -> ICL Translate Field Data Fix. However, you should first enable gzcompression on your server. Our second-tier supporters said things started working after enabling this function, even though we have not run the ICL Translate Field Data Fix plugin.

**** Important! Please make a full site backup (files and DB) before you proceed with those steps****

Regards,
Itamar.
