There is a z-index issue on translated content

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

Problem:
If you're experiencing an issue where the header on the English pages of your site appears under the page content when scrolling, and this seems to be related to a z-index issue with the Divi Builder header template, while the Dutch pages display correctly, we can help.
Solution:
First, ensure that no custom CSS or settings specific to your site are causing this issue. We recommend setting up a staging site to isolate the problem. On the staging site, disable all plugins except WPML and any necessary for login. Then, check the Post Types Translation settings under WPML > Settings > Post Types Translation and compare these with a clean installation. Adjust any settings that differ.
Next, go to WPML > Translation Dashboard, send the homepage header for translation, and complete the translation. Afterward, edit the header in Divi > Theme Builder and ensure the z-index value is set correctly (e.g., 999).
This solution is a workaround and under normal circumstances, it should work without these adjustments. If the issue persists or if the solution seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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 needed, please open a new support ticket at WPML support forum for further assistance.

deshnav	On the english pages of my site the header is under the page content on scroll. This seems to be a z-index issue on the translation divi builder header template. On the Dutch pages this is fine. Can you resolve this, or provide at least a css fix. This is a serious issue.

deshnav	Hi, I cloned the site to hidden link and disabled plugins to see if there was anything causing this issue. Now only wpml and temporary login plugins are active This is the temporary login link: hidden link

Dražen Supporter Languages: English (English ) Timezone: Europe/Zagreb (GMT+02:00)	Hello, thank you. I checked and tried to reproduce the issue on a clean setup, where everything works correctly. This indicates that the problem is specific to your website or environment. I noticed that some default Divi settings for post types were manually changed, and possibly other settings as well, since the issue does not appear on the test sandbox site. To fix the problem, I reviewed the Post Types Translation settings under WPML > Settings > Post Types Translation and compared them with a clean test installation. I then applied the correct configuration on your staging site. After that, I went to WPML > Translation Dashboard, sent the homepage header for translation, and completed the translation. Then I opened Divi > Theme Builder, edited the EN header, and set the same header z-index value (999) that you are using. What I shared is a quick workaround for your issue, but this should normally work out of the box as it is on test site, but since I’m not fully aware of all changes made on your site, I recommend comparing your setup with our test site and reverting Divi translation settings for custom fields, post types, taxonomies, and terms to the correct configuration that you / some one else changed on your website. Hope this helps, let me know how it goes and if any doubts. Regards, Drazen

deshnav	I followed this instruction and now the header is on top of other content again. I could not have dome this without your help, so thank you. I have been working with translations on this site since summer 2025 so probably changed settings while settings troubleshooting.
