Description:
Hi all,

I have the same issues as described at https://community.bitnami.com/t/error-500-after-install-openproject-11-1-0/90295.

I'm getting unregularly recurring error 500 messages when working with OpenProject 11.1.2 on Bitnami Virtual Machine (Debian 10.8, VMware ESXi 6.7 U2).

Sometimes I get a more detailed error message: "Ein interner Fehler ist aufgetreten. Permission denied @ rb_sysopen - /opt/bitnami/apps/openproject/htdocs/tmp/cache/[...]".

The permissions of the cache folders are set as shown in the linked thread.

After refreshing the site in the browser the error disappears and you can go on with working until this error appears on another site of OpenProject.

Here is an excerpt of the access_log of the apache web server:

Here you can see the recurring error 500 although there are no issues for the same request on an earlier timestamp.

It's not possible to open a case at OpenProject because they don't support the installation on a Bitnami system.

Please help.

Thank You

Hi @TheExpert,

How often does the error occur? Is there a way to easily reproduce it? Did you change any configuration files or install any plugins?

Hi @michiel,

this error happens very unregularly and there's no real way to reproduce it in a safe way. I see it for example when changing the sites in the user administration.

Kind Regards

Hi @TheExpert,

I haven't been able to reproduce it yet. Did you change any configuration files?

Michiel

TheExpert 2021-02-17 08:17:35 UTC #5

Hi @michiel,

no, I didn't change any configuration files. I imported the complete OpenProject database from an old UCS server to the new Bitnami appliance.

Hi @TheExpert,

It seems some folders in the 'apps/openproject/htdocs/tmp/cache/' are owned by the root user and group. Could you try changing the group for the files in the cache folder recursively?

sudo chown -R root:daemon /opt/bitnami/apps/openproject/htdocs/tmp/cache

Hi @michiel,

after doing that I only get this error:

"Internal error
An error occurred on the page you were trying to access.
If you continue to experience problems please contact your OpenProject administrator for assistance.

If you are the OpenProject administrator, check your log files for details about the error."

Before changing with your setting the most folders had "daemon:daemon" and some others had "root:daemon" as owner. When setting "daemon:daemon" as owner it seems to work. Shouldn't then the owner be set to "daemon:daemon"?

Kind Regards

Hi @michiel,

I did some work with OpenProject (changing tasks etc.). Until now, there were no error messages anymore.
