On the one hand, please note that changing the owner permissions must be done very carefully. Whenever you do a change like that, please note down what permission configuration you had previously.
We have a Support Tool that will gather relevant information for us to debug the issue. Could you please download and execute it on the machine where the stack is running?
You can log in your server via SSH and just type the following to download the tool:
wget -O bnsupport_tool https://downloads.bitnami.com/files/bnsupport/latest/bnsupport-linux-x64.ru && \
chmod +x bnsupport_tool && \
You will be prompted to indicate the directory where your stack is installed (which is /opt/bitnami on VMs and Cloud Images by default).
NOTE: The tool will inform you about the information that will be shared with us and you can decide whether to share it or not. Please review it and ask us any doubt you have if you do not agree with sharing some of the information.
After that, please, copy the hash on this thread.
Apart from the information gathered from the Bitnami Support Tool, please run the commands below and share with us the output:
ls -la /opt/bitnami/apps/suitecrm/
ls -la /opt/bitnami/apps/suitecrm/htdocs
ls -la /opt/bitnami/mysql
