Error when uploading files to wordpress even with propper folder permission

Question

I Just installed a new wordpress into a EC2 Server using Bitnami.

I tried to upload an image but I'm getting the fallowing error:

logo.png Unable to create directory uploads/2018/07. Is its parent directory writable by the server?

By using SSH I already give all permissions to the ENTIRE wp-content folder (yes I was desperate)

total 32
drwxrwxrwx  8 bitnami daemon 4096 Jul 21 19:57 ./
drwxrwxrwx  6 bitnami daemon 4096 Jul 23 19:48 ../
drwxrwxrwx  2 bitnami daemon 4096 Jul 21 16:20 ai1wm-backups/
drwxrwxrwx  4 bitnami daemon 4096 May 23 18:34 languages/
drwxrwxrwx 14 bitnami daemon 4096 Jul 22 12:39 plugins/

drwxrwxrwx  2 bitnami daemon 4096 Jul 23 02:34 upgrade/
drwxrwxrwx 10 bitnami daemon 4096 Jul 21 16:20 uploads/

What can be happening???

A despite of, the directory 2018/07 already exists

bitnami@ip-172-31-56-156:/opt/bitnami/apps/wordpress/htdocs/wp-content/uploads/2018$ ll

Answer 1

I Found the solution. The problem was on settings, the "media save folder" was misconfigured by the previous administrator. I just removed the setting and it woks.

another option is removing this entry on wp_options mysql table
