These log files keep having the root user owner permissions which leads to that permissions error message!!!
As I previously worked out to run these commands:
sudo chown -R bitnami:daemon /opt/bitnami/apache2/htdocs/back-end
sudo chmod -R g+rwxs /opt/bitnami/apache2/htdocs/back-end
Then its cool… but does it come back when Laravel creates new logs?!?
