Upgraded to 1.9 but having trouble with the certificate module, is this a permissions problem?
FPDF error: Unable to create output file: /opt/lampp/moodledata3/12/moddata/certificate/2/534/Certificate for MDL Custodian/Trainer Course.pdf
I had the same problem. Take out the "/" in the name and it will work. Custodian Trainer Course.pdf.
Thanks, it worked. There are names with slashes in them that I had not noticed.
