It is possible that the Apache user (
daemon) does not have permissions to access the files in the
/opt/bitnami/frameworks/myapp. Also note you are defining the
calculadora app both as a VirtualHost and as a prefix app and that this is not possible. Please comment out the related line in the
/opt/bitnami/apache2/conf/bitnami/bitnami-apps-prefix.conf file and restart the Apache service for changes to take effect
sudo /opt/bitnami/ctlscript.sh restart apache
Regarding the permissions issues, can you send us the output of running the commands below?
ls -lart /opt/bitnami
ls -lart /opt/bitnami/frameworks
ls -lart /opt/bitnami/frameworks/*
Apart from that, I was not able to find the virtualhost definition you posted on your first message on your bnsupport bundle, but note that you are setting the DocumentRoot and the Directory directives for different locations.
Hope it helps,
