Hi, when i click on "Edit profile" it send me to : https://www.speedrun.com/user/editprofile

And when i use : https://www.speedrun.com/editprofile/user/u
it say : You cannot edit someone else's profile.

I'm stuck please help.

IDK how you're getting that link but try this
https://www.speedrun.com/editprofile

My guess is that your issues are because your username is a character that can’t successfully be resolved into a URL and “u” is a different profile/username than what you have.

@Timmiluvs I thought about it too, but when you search for user "u" both in the site and in the API,
you get the reference to the OP here with the dotted "u".

- @Lieutenant_Boo Thanks for the link "https://www.speedrun.com/editprofile" it work, and yeah idk why they don't send me to the good link either.

- @Timmiluvs ü is the same as u, they just allow special language accent but count as normal letter

So my profile have an bug that change all redirection to "https://www.speedrun.com/user/<something>" ( Except for Edit theme and info, idk why )
So it basicaly search for the user named like this ( funny bcs https://www.speedrun.com/user/pendingactions rly exist ).
"pendingactions" can be redirected if i remove the "/user/", "settings" too, but not "Allpost" for the forum posts.

Well my userprofile have a lots of bugs that i never had before.
