Hi,
Thanks for your prompt reply.
I have tried following your alternative solutions:
1. Resetting
2. Disabling header:
3. Change fonts
4. Switch Enable “Save as” option
5. Disable Saving PDFs in temp directory
6. Disable prevent output buffer (the default is already disabled though)
The output is as following, the PDF invoices are downloaded to my disk but unable to open the file, I don’t know what the issue is.:
