@julian Hello Issue is already fixed thanks to @Per0x It was Nginx yes, But now i have a problem. For some reason the forum don't load new profile pictures. Let me explain you; I upload my first profile picture, everyone can see it. But if i update my profile picture no one can see the new one until they delete Cache/cookies.

It's likely that this is a bug, not something you can easily fix. Open an issue on GitHub.

Hi, i fixed the problem by reinstalling nodebb. also cleaning all plugins and stuff, and no. I dont have nay custom plugin the only plugin i downloaded before this error was iframely recommended by the admins of this forum.

I've been waiting for days but i don't get any reply, i tried by googling my issue but same. The problem is that members of my forum can't update their profile pictures or banner. They change it but nobody can't see the new picture until they clear caché. How to fix that?

@julian yes
