This thread is resolved. Here is a description of the problem and solution.
Problem:
After performing MEDIA TRANSLATION in WPML, the header image on all Spanish language posts and pages appears broken.
Solution:
We recommend checking the issue related to SVG support when activating WPML Media, which might be stripping parts of the image URL. You can find detailed information and a potential fix here: SVG Support - Activating WPML Media strips uploads folders from SVG image URL.
If the header image remains broken after applying the suggested fix, please try re-uploading the image. If these steps do not resolve the issue, it might be due to a different cause or the solution might be outdated. 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 problem persists, please do not hesitate to open a new support ticket for further assistance. You can do so here: WPML Support Forum.
