Give blocks PDF-Creation

Hi,
I’m using the plugin germanized with woocommerce to create pdf-invoices.
Since I have installed the Give-plugin I can’t create new pdfs: PDFCREATE error.

The Germanized-support responded:
Hi, Gregor,
unfortunately there seems to be a problem with the TCPDF library (which is apparently used by Germanized and Give). Germanized only loads the library when it is really needed (as soon as the invoice is generated). This is apparently not the case with Give, and this again leads to the problems. I think you should contact the give support about this and ask them to load the library only when they need it.

How can I solve this now?

BR
Gregor
