This thread is resolved. Here is a description of the problem and solution.
Problem: When switching to English, all texts remain in German, and the header is not visible. Solution: If you're experiencing issues with texts not translating and headers disappearing when switching languages, it's likely due to unregistered Elementor widgets. We recommend registering your custom Elementor widgets for translation. You can learn how to do this by following our guide on registering page builder widgets.
We have registered the elements in your header and footer, and they should now appear correctly translated. If you encounter untranslated content on other posts or pages, you should contact the theme authors to ensure they register the custom elements they created. You can refer them to the same guide.
Additionally, you can add the necessary XML code for registration in WPML -> Settings -> Custom XML Configuration tab as outlined in the guide.
If this solution does not resolve your issue, or if it seems outdated or irrelevant to your case, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix,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 problems persist, please open a new support ticket.
This is the technical support forum for WPML - the multilingual WordPress plugin.
Everyone can read, but only WPML clients can post here. WPML team is replying on the forum 6 days per week, 22 hours per day.
I checked the texts, and it seems you use some Elementor widgets that need to be registered before translation. Please check this guide to know more about registering page builder widgets.
I'm not using anything. Everything on the website is the original theme; we haven't implemented any custom widgets. The theme is 100% original, just as it was delivered.
Although I went ahead and registered many custom elements, this is the responsibility of the theme authors; therefore, it falls outside of our scope as a WPML technical support service.
Please tell us exactly which settings you have changed. We can no longer perform a WordPress update. When we click on "Update," we are redirected to this page, and the backend is extremely slow!
Please list all changes you have made to the code or WPML settings.
And what am I supposed to do with that? Tell me why I can't update anymore since they started working. The problem is new. Two days ago we updated WordPress without any problems.
