I am puzzled by this bug that hit some time ago. I gave it some time to disappear, and this morning I tried changing the affected categories to see whether it would disappear, but it’s still there, forbidding access to a category that has been there for years.
Symptoms
I have a subcategory with (full) slug asbl:editions. I have another subcategory incoming:ps-editions-lesoiseaux-io. The latter is more recent.
Whenever I tried to move a topic to the former category, or create a new topic there from the home page, etc., when I type editions, I only get the latter in the list, and not the former.
There’s no log, no console error: it’s just not there.
This is very annoying because it’s a very important category and many times I need to move relevant topics there.
Troubleshooting
I would like some guidance to understand how to track down this bug, because there’s no obvious way to do so. This is the only affected category.
I tried:
- removing the slug and saving

- removing the slug and saving in the other category

- renaming the category to WTF: it appeared again in the dropdowns

- renaming the category back to its original name (
Éditions): it disappeared again…
I wonder if there is a reserved word issue, or some kind of confusion across category slugs, tags, groups… I have no duplicate name but variants: ps-editions, editions-ps, etc. that use the single word that is the missing category slug: editions. Maybe this is a lead?
Thank you for your helpful attention.
