Thank you, Mike and Yves, you were right, it was SELinux.

Kind regards,

Hi,

what does "getenforce" say? 

You cannot verify that SELinux doesn't cause the issue by trying to write a file to /tmp with the specific user. SELinux is more complex than this - trust us.

Cheers,

thank you for your answer but, as I said before, both users ‘otrs’ and ‘apache’ can write a file in that location via the command line.

Any other idea?

Kind regards,

Hello

Probably "Step 7: File Permissions" from https://otrs.github.io/doc/manual/admin/4.0/en/html/manual-installation-of-otrs.html can help you solve your issue
