PDF invoices not generating after upgrade to 1.2.5

[JsusSalv]

Hello:

I upgraded my old 1.1 site to 1.2.5. Everything seems to work except for the PDF invoice generating function. When I click on any invoice from an order I get the following message onscreen: Invalid date

Any ideas on what's going on or a possible fix?

Thanks!

This is an old theme but anyway, here is a solution. When you are upgrading Prestashop, you have to copy some files fom previous versions to the latest version, if you modified PDF.php and PDF.html or if you added some extra Fonts.

These files are:
/prestashop/classes/PDF.php
/prestashop/classes/PDF.html
/prestashop/tools/fpdf/font/your-font.php

Hope, this helps,

Cheers
