Directory/File permissions and ownership

I am having some troubles getting 5.2.4 running without errors due to permissions for projeqtor.php.
2016-02-22 14:34:32.540 ***** ERROR ***** ERROR *****
2016-02-22 14:34:32.540 ***** ERROR ***** on file '/opt/bitnami/apps/projeqtor/tool/projeqtor.php' at line (324)
2016-02-22 14:34:32.540 ***** ERROR ***** cause = fopen(../tool/i18n/nls/lang.js): failed to open stream: Permission denied

I have configured ownership and permissions on the projeqtor folder identical to what I have for version 5.1.5 which is running successfully.

I tried to search for any documentation on setting ownership and permissions on the projeqtor folder and files but did not find much.

Currently I have the folder and files under projeqtor owned by myUser:daemon.
For permissions I set projeqtor and subfolders to 755 and files to 644.

For documents, attachments, logs, etcetera, I created a separate folder: projeqtor_files. I setup ownership as daemon:daemon and the permissions on all folders to 755.

Are these permissions correct?
