This thread is resolved. Here is a description of the problem and solution.
Problem:
You are trying to translate the header and footer of your Full Site Editing (FSE) theme into multiple languages using WPML. While other languages are translated successfully, the Finnish translation displays issues. Specifically, the header looks different and, on certain pages, the header and footer disappear entirely.
Solution:
The issue arises because the Finnish “header” template was initially created as an original rather than a translation of the Norwegian template. To resolve this, you should:
1. Copy the content from the Norwegian template (ID 7704).
2. Paste it into the Finnish template (ID 8371), replacing its existing content.
3. Apply this process to other languages to ensure all templates match the Norwegian original.
If this solution does not resolve your issue or seems outdated, we recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have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.

Hello, Welcome to the WPML support forum. I will do my best to assist you in resolving the issue. Please try the following steps after creating a full site backup, and then check if the bug still exists: 1) Upgrade to the latest version of WPML (4.8.1 series). If the issue persists, please create a post or page for testing, translate it into Finnish, and confirm whether the bug is still present. -- Bigul |

I've done the things and still have issues. This is a block theme developed by us, using the full site editor. The footer editor is not used, and we're using the full site editor footer template. To actually make the header & footer display on multiple languages, the header and footer FSE template needs to be translated (weird). The place to edit this is in the default WordPress full site editor. I've tried to both duplicate the header template, and manually translate the FSE gutenberg strings, neither updates on the finnish language, but on all other langauges. |

I checked languages folder for mo/po file discrepancies vs language code and hreflang, but I'm not seeing anything unusual. Can we try this? On this sandbox, can you install your theme and create simple header/footer and translate it (or at least duplicate as that will be quicker, but should still show the issue)? I will check with our 2nd tier then to see if this is perhaps a compatibility issue or a bug in WPML. |

I'm trying to upload the theme and required plugins via the WP installer, but when I click the "install" after uploading the zip nothing happens. I've given you guys access to my development site, shouldn't that be sufficient enough to debug this? |

Can you upload your theme into wp-content/themes into hidden link so I could try installing it? If that fails, to troubleshoot this problem, I'll install the Duplicator plugin and generate packages for further debugging purposes. I'll ensure to exclude all media files to maintain a minimal package size (I would do this on hidden link) You can find more information about the process here: Please confirm if this approach is acceptable to you! |

Actually can't; the php version supported on the link you sendt is too low. My theme is 8.2+, but it only supports 8.1 and below. |

I see. Ok, how about Duplicator approach then? I'll install the Duplicator plugin and generate packages for further debugging purposes. I'll ensure to exclude all media files to maintain a minimal package size (I would do this on hidden link) You can find more information about the process here: |

Duplicator sounds nice! Do you have all the permissions you need? |

I can create Duplicator package, permissions are sufficient. However I went on to check this again before escalating and I can see that header and footer show properly now. Can you check again and let me know if I am missing something? I check on both hidden link and hidden link but not sure I see something missing compared to the original language for either footer or the header. Can you send me some screenshots to illustrate what is missing? |

It seems like the header is back on the pages, that's good. However, the header menu does not update on the finish language, you can verify this by clicking the language switcher on any other language (the button top right on the navigation bar), where it works on any other language, and it does not work, and look different on the finish version. Also the styling changes, e.g. font-size, logo size, etc does not update on the finish header version, even when I duplicate the FSE templates. Steps I've tried to solve this issue: I've done this by going to Translation Dashboard -> selecting the chosen templates (Header, Sidetoppmeny, sekundærmeny) and sending them to either translation, or duplicating. Please ask any clarifying question if I'm missing some important information you need to understand what I've done 🙂 |

I tried to translate header template and navigation menu through advanced translation editor, but it has not helped either. Can you install https://wordpress.org/plugins/pexlechris-adminer/? I'd like to check something (will not change anything in database). |
