[แก้ไขแล้ว] categories

Contexte de la question:
I am trying to resolve an issue where clicking on any of the 8 categories on my site results in a 'page not found' error in all languages, including the default language. I want the categories to display correctly in all languages, either by keeping the same slug or using a different method. The issue can be seen on this page: ลิงค์ที่ซ่อนอยู่

Symptômes:
When I click on a category, I receive a 'page not found' error in all languages, and the categories do not display as expected.

Questions:
How can I ensure that categories are found and displayed correctly in all languages?
Should I create a new slug for categories in the future to avoid this issue?
