Thank you Joe...
I'm using Apache 2.2.6 + Windows XP + MySQL 4.0.27 ... I'm going to try to install it on Linux to see if it work that way. What version of PHP and Apache you think is more suitable?
I found also a bug on class.mail.inc and purchasing_ui.inc, that bug doesn't allow to use the purchase module, the problem is that it's missing the string "php" on the begining of the document.
Instead of "<?php" it says "<?", adding php solves the problem. I hope this could help someone.
I like to ask you also if there is any documentation of how the translation module works (gettext.php or all the translation thing). I have no experience with .MO files and I don't know how it works.
Thank you again,
Alfred
