Fixed and deleted duplicate versions of your mod.
Your mod can now be accessed via https://moddingofisaac.com/mod/1446/treasure-and-difficulty-mod

No, previous versions of mods are not stored.

You can delete you cookies to logout, but if you dont just delete cookies from moddingofisaac.com you will be logged out from most websites.

You logged in with a wrong account. If there are no error massages during login and you cant download mods then the accout used to login has no access to rebirth.

It is intentional, that you return to the page, you clicked login on. Permanent cookies must be enabled to login.

This appears to be a bug in the Mac version of the game. (I dont have a Mac, but thats what I read on reddit)

Try logging out and in again.

i did that very often and it didnt work, but i saw you somehow fixed it for others and i wondered if you could do the same for me

Logging in and out wont fix it if you dont own the game.

Its the website. Users that do not own rebirth have no access to certain features of our website, like up and downloading mods.

Can you please explain the problem? Write what you did, what you expected to happen and what happened.

Delete everything in resources except packed and you have a unmodded game. Also you could just delete everything and let steam download rebirth again.
