404エラーでグループを削除

[Canapin (Coin-coin le Canapin)]

Your issue reminds me a bit of this one with category names:

Click the edit button on the category page to go to page 404

Thank you! I didn’t like long slugs and had turned it off before. Selecting’encode’ for the slug generation method resolved the 404 error. In such a situation, I think that it could be prevented by not accepting multi-byte characters or if there was a cautionary note. In any case, it’s strange that the encoded string was assigned to the category that was emptying the slug …

Not sure at all it’s related, but maybe you can have a look.
