it's completely ready

domPDF does not have to be installed through installer. have you followed the instructions here? : http://www.joomlafinances.com/guide/invoices/installation

the white screen must be some kind of problem we're missing. can you maybe turn on error reporting on joomla global config so we can maybe see what's causing the issue?

if you prefer you can email me directly at joomlafinances@gmail.com

wooops
the dompdf is done, my bad...

white screen will be tested with error reporting. Will put the feedback here or sent you a mail.

Do you have any idea about the templates ? added screenshot.


Thanks.

and here you go for the errors...

many thanks.

the problem is just the last one:

this probably means that your PHP variable short_open_tag is OFF, and it should be ON.
can you turn it to ON?

you can now disable error reporting.

idd , i overlooked it at first... xampp had it turned off ...
great, one to go ;-)

The templates, got any idea on that issue ?

the template is fine. it is supposed to appear this way (HTML code), no editor will be rendered here unless you open it with the "editor" link.

but I don't recommend you that, because most HTML editors will mess up the code and it won't look good..
are you not familiar with HTML?

Oh ok, thought it had a handy editor ;-)
