Background of the issue:
I am trying to resolve an issue where 404 errors appear in the menu for all languages except our standard language, Swedish. This might have happened after updates. I have tried using the support function with ghost posts and cache, disabled all other cache functions, and attempted to update permalinks without success. The issue can be seen on this page: hidden link
Symptoms:
I expected to see a product category, but instead, I got a 404 error.
Questions:
Why are 404 errors appearing in the menu for all languages except Swedish?
What steps can I take to resolve the 404 error issue after updates?
I'm glad to hear you were able to resolve the issue! I deleted your comment on the errata page since it included your debug information and was publicly visible.
