Missing a temporary folder not fixed

I uploaded my first wordpress website on the server, but trying to add new media files, i have got the message “Missing a temporary folder”, I tried the solutions on the forum:

and created a ‘temp’ folder on ‘wp-content’, but the problem still happened ..
how to fix that please ??

I tried by doing this : creating the folder on localhost with writable property then upload it to the server, but it still doesn’t work
