Http error 500 export to PDF


Hello, until yesterday I was able to export as PDF my document.
Since today I get an HTTP error 500:

“status”: 500,
“headers”: {
“x-firefox-spdy”: “h2”,
“content-length”: “194”,
“content-type”: “text/html”,
“date”: “Tue, 05 Jun 2018 10:30:32 GMT”,
“server”: “nginx/1.13.10”
“body”: {}


I have the same problem. Export to pdf and i get either a 500 error or i download a pdf that cannot be viewed later in the browser.


Right now to me it says that the whole website is offline…


Should be fixed now. Sorry for the inconvenience.


yes working perfectly now.

May I ask two things while you read and answered?
How it is possibile to create a table of content and insert where I want it in the PDF export?
It is possibile to center tables and images when exporting to PDF?
