Hi @jonpbradley,
First, I would like to apologize for the inconvenience caused by this bug.
Please note that we have already solved it (here) and we should release a beta version soon.
That said, while we prepare the next public release, I recommend you to downgrade the plugin temporarily to the previous version, by manually installing the version 3.9.6, which you can get here: https://downloads.wordpress.org/plugin/woocommerce-pdf-invoices-packing-slips.3.9.6.zip
If you’re wondering about the cause of this bug, it was introduced in the latest version (4.0.0), because the WordPress.org Plugin Team asked us to apply some changes to be compliant with their current requirements, therefore, we added stricter sanitation and security methods for data insertion fields, like the shop data fields, but the HTML cleanup we developed is very strict, producing this kind of behavior when you have used specific HTML tags or attributes that are not allowed by default.
We have decided to use a less strict function for the shop fields (the wp_kses_post function provided by WordPress), since these fields are not filled externally, but by the shop manager instead. However, we continue using our own sanitation method (wpo_wcpdf_sanitize_html_content) to clean other fields, like the details provided by the customers (addresses, notes, etc.)
I’ll keep you posted as soon as the new version is available!
Thanks for the quick reply – downgrade works! I’ll keep an eye out for the new version.
