After having upgraded from 1.5.3 to 1.5.4a, I have the following errors on all pages that used PDFLib :
Fatal error: Call to undefined function PDF_begin_document()
It sems it's caused by an older version of PDFLib (5.x instead of PDFLib 6.x)
Will it be possible to get PDFLib 6.x back in later versions of XAMPP?
