Hi again @impactelemental,
I've tried myself to reproduce this on my side: launched a fresh Bitnami WordPress VM, enabled the "All-in-One WP Migration" plugin and imported a backup (created with the same plugin) successfully.
Could you please check that your
wp-content/uploads has the correct permissions and owner? It should be like:
$ ls -la /opt/bitnami/apps/wordpress/htdocs/wp-content/uploads/
drwxrwxr-x 3 bitnami daemon 4096 Dec 19 10:22 .
drwxrwxr-x 7 bitnami daemon 4096 Dec 19 10:22 ..
drwxrwxr-x 3 daemon daemon 4096 Dec 19 10:22 2018
If it differs from this, you should be able to fix it with these commands:
sudo chown -R bitnami:daemon /opt/bitnami/apps/wordpress/htdocs/wp-content
sudo chmod -R g+w /opt/bitnami/apps/wordpress/htdocs/wp-content
Looking forward to your feedback,
