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

Problem:
The client is experiencing an issue where the menus disappear from the 'Appearance' section in WordPress, displaying only 'Create your first menu below', despite already having menus. Additionally, switching the website's language sometimes shows all the menus, but this is inconsistent and depends on the language, specifically Norwegian in this case. Attempts to use WP-menu sync have resulted in crashes, and the menus sporadically reappear and disappear.
Solution:
We recommend trying to synchronize the menus again. However, it's crucial to ensure that you have a backup of your current menu settings before proceeding to avoid any loss of configuration. If you have a backup, we can attempt to restore and fix the menus without using the menu sync feature, which seems to be causing instability. If the issue persists or if you do not have a backup, please visit the WPML support forum for further assistance.

Please note that this solution might be outdated or not applicable to your specific case. We highly recommend checking the related 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 continues, do not hesitate to open a new support ticket.

I have an issue, where the menus from my website dissapear under "appearance".
The only thing I get is "Create your first menu below"
But I already have menues.

And the second thing, is if i change language i can get all the menues shown in another language.
But I have to look at which language it is. So in this case "norway" shows all the menus. See attached imags.

I have tried WP-menu sync but that just crashes.
And all of a sudden the menus can reapear.
And then the same issue appears again after a while where they care gone.

Hi there!

Do you give me permission to download a copy with Duplicator?

That way I ca investigate the issue without affecting your site.

Hi, Sorry for my late reply.
I did not get a notification about this.

I can setup a staging website if you want and give you access to that one?

Also, I have been having this issue, and it's almost everytime I do a plugin update.
Never had this issue before and I have been using WPML for many years.

Yes, please create a staging site so I can investigate safely and, if needed, escalate the issue to our second-tier team for further analysis.

Hi there!

I have retranslated the menu and now appears correctly for the staging menu.

Could you please check if everything is correct on the staging site?

Hi,

If i go to the Swedish language on frontend.
The menu now shows ENG menu options.
And there are missing submenus.

So something is still wrong.

The ones that doens´t appear translated is because there are custom links and you need to translate it from WPML --> String translation.

I see from here everything correctly: hidden link

I see that you have added new items to the menu you will need to re-synchronize.

I am not relly following here.
Looking at the Swedish langauge on frontend, this is what I see (see attached image).
This was never an issue before.

And I never did a string translations on the menu items, since the menu is and can be different in other languages. So not always the share the same menu structure. And that is how I want to keep it.

And if i select "Wp menu sync". After a while i get a 404 error so I can't do a sync.

In order to fix the problem I have synch the menus again, the thing is that now it change what you had.

Do you have a backup of what you have before on the menus?

That way I can fix the menu issue without menu sync.

Hi,

This is a staging site, and the main purpose for it was so you could help me identify the issue with the menus disappearing under Appearance. So, I don't have a backup of this staging site.

Only thing I can do is removing this staging site and create a new one. But then we are back at the original problem.
