I’m confused as to why I’m getting this error message when trying to generate PDF previews:
This has just started happening from making a custom template. Now every time I attempt to make a invoice, this shows up in the preview below it.
This is a self-hosted instance running on PHP 7.x and the latest stable Invoice Ninja.
Please advise on what to do next as I have some client invoices to generate and well, PDF functionality is currently broken for my installation.
