after we upgraded our forum to 2.4.0beta6, we noticed that various categories lead to a 404 error page.
And after you reach this 404 error page, when you hit the forum logo (to go the home page) it just stays in the 404 page. So, we suspect the front-end reaches a “bad” state.
This call returns a 404:
If it helps, sometime in the past, we changed our slugs from Encoded back to ASCII. But as it seems, the categories slug never changed. We tried changing the slugs from ASCII to Encoded, but nothing changed. (deleted cache etc.)
You can see the problem on our discourse instance: https://rembetiko.gr
Any suggestions? We suspect some kind of bug here…
