White Screen of Death in Cart Confirm, in Invoices and Print Order

[masto93]

Hi everybody.
I had a problem, but now are two. Let me explain: I had a malfunction in the functions of generation of invoices, and printing order. To try to solve the first thing, I made the safe path for sales and invoices as suggested by VM. Once done this operation, the problem has gotten worse, in fact now for some functions I have White Screens of Deaths (Internal Server Error - 500). The features that give this problem are:
- The confirmation of a cart's order,
- The generation of invoices (and also the printable orders).

I'm using  VirtueMart 2.9.9a  - Joomla! 2.5.27  -  PHP 5.4.35.

It seems to not be a template problem, and VMdebug does not helped me for this...hope you will

Please update to vm3.0.2 first

hi,
I've updated to vm3.0.2. The results are:
- I can confirm orders
- I can see the printable version of orders

But
- I still have White Screen of Deaths (Internal Server Error - 500) in the generation of invoices and delivery notes

what can generate this error ?


EDIT: * now the colour custom field does not works
(sorry for my English)

Did you updated your AIO? the tcpdf?
furthermore check the descriptions and info of your payment, I just had the case that the html code was scrambled and so tcpdf failed hard.

I've update AIO and the tcpdf, but the issue persists.
Descriptions and info of payments seems to be normal, but how can i verify if html code is scrambled?
Is there anything else that i can try?
thank you.

new step: i've re-istalled tcpdf for the second time and now instead of WSODs appear the following error:

TCPDF ERROR: The XObject Template '-1' doesn't exist!

i've tried to identify the php file that generate this error (for example components/com_virtuemart/views/invoice/...) but i cannot solve it.
any ideas? thank you

Do you use any overrides? the html for pdf is stricter than for most browsers.

[masto93]

I verified if there were some override here: /mysite/mytemplate/html/com_virtuemart/... but it seems that there is no override for the php that generate invoices.

It maybe could help: here is a list of directorys in /mysite/mytemplate/html/com_virtuemart/... , where should i verify if is there any override?
/cart
/category
/productdetails
/sublayouts
/user
/index.html

Thank you for the attention
