How To Fix WordPress Upload Directory Not Writable

I migrated a WordPress site between VPS machines.

I had an issue after the migration where this error was on my admin dashboard

I checked Site Health and confirmed that all other folder permissions were ok but the uploads directory was not writeable.

I double-checked on my VPS and the folder was writeable.

I finally found the solution and it was my error.

I am using Server Avatar to manage my VPS and in the migration process, I unknowingly changed the migration directory case of the domain from xxxx to Xxxx.

I logged into PHPMyAdmin, selected my WordPress website database table and selected the wp_options table. Located “upload_path” row and changed the casing of the path there, saved and it worked.
