I keep getting errors while trying to create a PDF. I used to be able to export the same file as a PDF before, but now it's giving me an error.
What error message?
what PDF export settings do you use?
Frequently, when you get errors when creating a PDF, it's because of the content on one page. Here's a troubleshooting technique to narrow down the problem: (1) Create a PDF of the first have of the document.
(2) (A) If it succeeds, the first half of the document is OK, and create a PDF of the second half of the document.
(3) Likely, you'll get an error on the second half. With the half of the document that failed, create a PDF the the first half of that section, then the secomd half. Continue until you find the page when the failure is occurring.
It's likely to be a graphic or possibly a font which exists on that page. Replace the graphic or font, and see if it succeeds.
