we are using the 3.3.2 community edition. In some cases when I run a sub-case an output document is not created. Instead the following error message appears:
TCPDF ERROR: Unable to create output file: /opt/processmaker/shared/sites/workflow/files/759/435/221/5d49f773006fe6008486196/outdocs/5815823945d49f798c500f0058706249_1.pdf
Funnily this does not always happen.
Have you encountered this problem before?
