Invalid font name to the PDF document when exporting PDF

[Vincent Wong]

I have a document that uses confluence for live documentation.

I successfully exported it for a long time, but when I tried to export it as a PDF today, confluence returned a error. I have tried to remove the newly added things, and it still returned with the same error...

The error received:
We couldn't complete your export. Exception thrown while rendering the page 'null' due to exception com.lowagie.text.DocumentException: Invalid font name to the PDF document

Any idea how to fix it?

We have same problem. Its not possible export single page.
