Hello Fernando, thanks for your answer. The problem is still the same for me either in ssh or sFTP. Sorry I am a newbie in cloud/unix installation.
It seems that bitnami daemon have rw authorisation and user bitnami only read.
I need the authorizations rights on resourcespace folder for changing css, images, php files. And for configuration of config.php page. The ability to download collections needs to be configured via the config.php page. You can make the change through your GoogleCloud engine by editing the PHP page said your support.
Here is the screenshot of config installation. It seems that the app doesn’t have the rights to write in plugin and gfx folder as well…
