@pomegranate I’m getting this error after activating WooCommerce PDF Invoices & Packing Slips + mPDF with all templates (tried: simple, simple RTL, simple mpdf).
in the log file I did find two types of errors:
2022-01-25T09:22:23+00:00 CRITICAL Error detected. PDF file generation aborted: Trying to access array offset on value of type bool
2022-01-25T13:39:32+00:00 CRITICAL Cannot find TTF TrueType font file "DejaVuSerifCondensed.ttf" in configured font directories.
