Does what it should, but has problems with PDF Library

It does everything like expected. But i have problems generating my PDFs for orders. Using German Market Plugin here. If Packlink is active it doesn’t work with PHP 8. Only if i use PHP 7.4.

I had send this issue above one year ago to the support, but nothing changed.

Here is what they said:

“German Market uses the PHP library “FPDF” to generate PDFs for delivery notes and return slips.
If this library already exists in another plugin, German Market will not include it again, but use the files already included.
Apparently the FPDF library in the “Packlink Pro Shipping” plugin is deprecated. The plugin should use a current version of FPDF. You would have to contact the support of this plugin.”
