A few minutes ago, I tried do adjust my profile: change email, main location. When I clicked in the “save changes” button, I was presented with a 404 page!
The address: “https://www.openstreetmap.org/user/383839”
"File not found
Couldn’t find a file/directory/API operation by that name on the OpenStreetMap server (HTTP 404)
Feel free to contact the OpenStreetMap community if you have found a broken link / bug. Make a note of the exact URL of your request."
This must be fixed, I need to change my email, at least. The current address does not exist anymore.
