I noticed a little bug on Discourse, and I managed to find the steps to reproduce it :
- Edit a category that has a logo and change the parent category
- After 24/48 hours, the logo image will give an error 404, you’ll have to reupload the logo.
It may happen when we edit something else, like the description but I only tried this steps two days ago, and I can confirm tonight that there is a little bug here.
My forum was up to date at the time. And I didn’t see anything related to this issue since. If it’s the case, my apologies.
