@CHBMB @alex-phillips ?

Double checked this on my dev system (Ubuntu 20.10 host), Seems to work fine when adding WKHTMLTOPDF=/usr/bin/wkhtmltopdf to the .env file.

Couple of questions that may help diagnose this.

• Does this error occur when exporting a single, very simple page?
• Have you set anything in the "Custom HTML Head Content" setting?

Removing the Custom HTML does indeed fix it...

@danielfaulknor Cool, Thanks for confirming. Likely not something that the lsio team can do anything about then so probably worth closing this to save their time.

If you can nail down what might be causing this in that code then feel free to raise on https://github.com/BookStackApp/BookStack/issues, it might be the case we have to filter stuff out or provide some level of non-export custom HTML content.
